Question

Solve the exponential equation 3^4x-1=3^31

Answer 1

Hello from MrBillDoesMath!

Answer:  x = 8

Discussion:

I interpret the question as follows:

3^(4x-1) = 3^31             find x.

Since the above bases are both 3, we need to equate their exponents and solve.:

4x-1 = 31                      -- subtract 1 from each side.

4x = 32 =>

x = 8

Thank you,

MrB
