Question

Solve for the following logarithmic functions: (a) log3 (2x-1) = 2 x = Answer 4 (b) logx 16 = 2 x = Answer 5 and Answer (Note: enter the answers in increasing numerical value)

Answer 1

Answer:

Solution

Use the equivalent expressions : y = log b (x) ⇔ x = b y to write

a) logx (a) = c as an exponential a = x c

b) logb (2x + 1) = 3 as an exponential 2x + 1 = b 3
