Answer:

12

Explanation:

Hi!

Here is your answer,

I will explain in step by step,


{x}^(9) = {12}^(2) * {12}^(7)

Here we can simplify this further using this law,


{a}^(m) * {a}^(n) = {a}^(m + n)

So we will get,


{x}^(9) = {12}^(7 + 2) \\ {x}^(9) = {12}^(9)

Since the powers are same we can cancel it out and we will get,


x = 12

(Hope this answer helped :))
