Question

9^x-2 = 27

Answer 1

Hint: rewrite 9 as 3^2 and 27 as 3^3

Answer 2

Then you can say

9^(x - 2) = 27

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

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

Answer 3

would the answer be...
x=2.5?

Answer 4

get it

Answer 5

i just tested you its not 2.5

Answer 6

Check:

9^(x - 2) = 27

9^(2.5 - 2) = 27 ... plug in the *possible* solution x = 2.5

9^(0.5) = 27

3 = 27

The last equation is false, so x = 2.5 is NOT the answer

Answer 7

the bases are the same in 3^(2(x-2)) = 3^3

so the exponents are the same: 2(x-2) = 3
