5^p-3 x 3^2p-8 = 5² x 3²
p - 3 = 2
p = 2 + 3 = 5
2p - 8 = 2
2p = 8 +2 = 10
p 10/2 =5
So p = 5

Hey there !
We need to factorize the Right hand side to make it resemble the Left hand side

Comparing both sides,
p - 3 = 2
=> p = 3 + 2 = 5
2p - 8 = 2
=> 2p = 10
=> p = 5
5 satisfies both values, So p = 5
