What is 8(5 to the power of x) equal 23?

Answer 1

8 × 5^x = 23

→ 5^x = 2.875

→ x log 5 = log 2.875

→ x = log 2.875 ÷ log 5

(You can use logs to any base as long as the same base is used for both of the logs.)

Answer 2

I assume you want to solve for "x". Why don't you start getting rid of the "8" - divide both sides by 8. After that, the next step involves taking logarithms on both sides.
