Question

3^(7−2x) = (1/27)^(−8) Solve the exponential equation for x

Answer 1

Answer:

Step-by-step explanation:

Your first job is to make the bases the same. Once you have done that, you can equate the powers.

(1/27) ^ (1 /- 3) = 3

(1/27)^(1/-3)(24)

3^24 = 3^(7 - 2x)

24 = 7 - 2x                   Subtract 7 from both sides

17 = -2x                        Divide by -2

-8.5 = x
