Question

If 5 Superscript 3 b minus 1 Baseline = 5 Superscript b minus 3, what is the value of b?.

Answer 1

It sounds like you're given

`5^(3b-1) = 5^(b-3)`

Since the bases on either side match (5), the exponents must be equal. So

3b - 1 = b - 3

Solve for b :

3b - b = -3 + 1

2b = -2

b = -1
