Answer 2

Answer:

196

Step-by-step explanation:

to equate the following we first have to make the integral part equalin both the cases

so

7^(x-5) = 7^3^2              {343=7^3}

=x-5=3^2                       {if the integral part is same on both of the sides of a        equation then the exponential part also becomes equal}

=x-5=9                       {3^2=9}

=x=9+5=14

14^2 = 196
