Unlike Terms ? 4x3 , 2x5 Like Terms ? 2x2 , 3x2 When multiplying terms with the same base When multiplying terms with the same base (x2) When multiplying terms with the same base (x2)(x3) When multiplying terms with the same base (x2)(x3) same base When multiplying terms with the same base just add the exponents (x2)(x3) When multiplying terms with the same base just add the exponents (x2)(x3) = When multiplying terms with the same base just add the exponents (x2)(x3) = x When multiplying terms with the same base just add the exponents (x2)(x3) = x2 When multiplying terms with the same base just add the exponents (x2)(x3) = x2+ When multiplying terms with the same base just add the exponents (x2)(x3) = x2+3 When multiplying terms with the same base just add the exponents (x2)(x3) = x2+3 = When multiplying terms with the same base just add the exponents (x2)(x3) = x2+3 = x5 When multiplying terms with the same base just add the exponents 2x2 When multiplying terms with the same base just add the exponents 2x2• When multiplying terms with the same base just add the exponents 2x2•4x3 When multiplying terms with the same base just add the exponents 2x2•4x3 = When multiplying terms with the same base just add the exponents 2x2•4x3 = 8x5 5x3 • 4x7 = x 3x4 • x = x When dividing variables with exponents When dividing variables with exponents subtract the exponents When dividing variables with exponents subtract the exponents x5 When dividing variables with exponents subtract the exponents x5 When dividing variables with exponents subtract the exponents x3 x5 When dividing variables with exponents subtract the exponents x3 x5 = When dividing variables with exponents subtract the exponents x3 x5 = x When dividing variables with exponents subtract the exponents x3 x5 = x5 When dividing variables with exponents subtract the exponents x3 x5 = x5- When dividing variables with exponents subtract the exponents x3 x5 = x5-3 When dividing variables with exponents subtract the exponents x3 x5 = x5-3 = When dividing variables with exponents subtract the exponents x3 x5 = x5-3 = x2 When dividing variables with exponents notice we use top minus bottom subtract the exponents x3 x5 = x5-3 = x2 When dividing variables with exponents notice we use top minus bottom subtract the exponents x3 x5 = top x5-3 = x2 When dividing variables with exponents notice we use top minus bottom subtract the exponents x3 x5 = top bottom x5-3 = x2 When dividing variables with exponents subtract the exponents x5 x3 When dividing variables with exponents subtract the exponents x5 x3 = When dividing variables with exponents subtract the exponents x5 x3 = x3 When dividing variables with exponents subtract the exponents x5 x3 = x3- When dividing variables with exponents subtract the exponents x5 x3 = x3-5 When dividing variables with exponents subtract the exponents x5 x3 = x3-5 = When dividing variables with exponents subtract the exponents x5 x3 = x3-5 = x-2 Since the exponent is negative When dividing variables with exponents subtract the exponents x5 x3 = x3-5 = x-2 Since the exponent is negative When dividing variables with exponents subtract the exponents x5 x3 = x3-5 = x-2 Negative exponent Since the exponent is negative When dividing variables with exponents the x moves to the denominator subtract the exponents x5 x3 = x3-5 = x-2 Since the exponent is negative When dividing variables with exponents the x moves to the denominator subtract the exponents x5 x3 = x3-5 = x-2 1 denominator Since the exponent is negative When dividing variables with exponents the x moves to the denominator and the exponent becomes negative subtract the exponents x5 x3 = x3-5 = x-2 1 Since the exponent is negative When dividing variables with exponents the x moves to the denominator and the exponent becomes positive subtract the exponents x5 x3 = x3-5 = x-2 1 = x2 1 x8 x2 = x 9xy2 6x6y4 = x y Negative exponents always go Negative exponents always go the opposite place Negative exponents always go so if the negative exponent is in the numerator the opposite place Negative exponents always go so if the negative exponent is in the numerator the opposite place x-3 1 Negative exponents always go so if the negative exponent is in the numerator it moves down and becomes positive the opposite place x-3 1 Negative exponents always go so if the negative exponent is in the numerator it moves down and becomes positive the opposite place x-3 1 = 1 x3 Negative exponents always go so if the negative exponent is in the numerator but if the negative is in the denominator it moves down and becomes positive the opposite place x-3 1 = 1 x3 Negative exponents always go so if the negative exponent is in the numerator but if the negative is in the denominator it moves down and becomes positive the opposite place x-3 x-3 1 1 = 1 x3 Negative exponents always go so if the negative exponent is in the numerator but if the negative is in the denominator it moves down and becomes positive the opposite place x-3 x-3 1 1 = = 1 x3 Negative exponents always go so if the negative exponent is in the numerator but if the negative is in the denominator it moves down and becomes positive the opposite place x-3 x-3 1 1 = = x3 1 1 x3 Negative exponents always go so if the negative exponent is in the numerator but if the negative is in the denominator it moves down and becomes positive the opposite place x-3 x-3 1 1 = = x3 1 1 x3 it moves to the numerator Which of these variables move? x, y, z x, b, c a, b, c a, y, z x-2yz2 ab-1c-2 When taking a power to a power When taking a power to a power (x2)3 When taking a power to a power the exponents are multiplied (x2)3 When taking a power to a power the exponents are multiplied (x2)3 = When taking a power to a power the exponents are multiplied (x2)3 = x2•3 When taking a power to a power the exponents are multiplied (x2)3 = x2•3 = x6 (x4)3 = x |
