The second of 4 skills relating to logarithms actuallydoes not require any logs at all. If the bases are equal then the expressions mustbe equal. The example below is a base "7" problem. If log7(x) = log7(y) and since log7 = log7 then x = y. Solving Logarithmic Equations equal bases equal expressions Since bases are equal, equate the expressions. Example: When bases are equal. -5x - 2 = 2x + 6 +5x +5x -2 = 7x + 6 -6 -6 -8 = 7x equal bases Solving Logarithmic Equations -1.14 = x -8 = 7x 7 7 equal expressions DONE! Solve for k. Bases are equal, equate the powers. What is the base ? Answer: Round to hundredths (ie. 2.34 or 0.63 or -2.00) Solving Logarithmic Equations Solve for x. Bases are equal, equate the powers.
