The answer is 5

Step-by-step explanation:

3² x 3ˣ = 3⁷

» 3ˣ = 3⁷/ 3²

» 3ˣ = 3⁵

Answer 2

Answer:

3²×3^x=3⁷

On LHS, bases are same , hence power will be added.

3^(2+x)=3^7

On both sides, bases are same , hence power can be equate.

So, it will become

2+x=7

x=7-2

x=5

The value of x is 5.
