Multiplication: when the base is the same, add the indices. Complete: and the missing power is....... 54 x 5 = 59 72 x 76 = 7 37 x 34 = 3 e.g. 53 x 54 = 57 Complete: Division: when the base is the same, subtract the indices. and the missing power is....... 38 ÷ 3 = 32 212 ÷ 25 = 2 67 ÷ 64 = 6 e.g. 59 ÷ 52 = 57 Complete: Power to a Power: multiply the indices. and the missing power is....... (52) = 516 (32)6 = 3 (75)4 = 7 e.g. (53)4 = 512 Complete: Zero Index: any value, to the power of zero, equals 1. 5 + 90 = But... 120 = e.g. 70 = 1 30 = 97 ÷ 91 = 9 32 x 35 = 3 x0 = Mixing it up....... 69 ÷ 68 = 6 5 x 54 = 5 (415)2 = 4 52 × (52)4 (53)2 Combining the rules.... = 52 × 5 5 = 52 × 58 56 = 556 = 5 (35)4 × (30)5 33 × 35 and again....... = 3 × 3 3 = 320 × 30 38 = 3 38 = 3 |
