Answer: a. x = -2 the answer. C. x = 0 the answer: a. Correct solution x= -1/4 the answer: a. x = 1/7 the answer. Step 1 : 32x + 2 = 3x. Step 2 : 2x + 2 = x. Step 3 : 2x - x = -2. Step 4 : x = -2 the answer: 52x-1 =0. Step 2 : 2x - 0 = 0. Step 4 : x = 0 the answer. Step 3 : x = 0 the answer: a. Step 6 : x = -1 the answer. Correct solution x =-1/4 the answer: a. (1/2)5x+1=4x-1. Step 5 : x = 1/7 the answer. Step 3 : x = 2 the answer: yes it is tru that logarithms are used to solve exponential equation with different bases, 4x+1=7. Step 2 : (x+1)log 4 = log 7. Step 3 : x+1 = log 7/log 4.
