5^(x-3 )× 3^(2x-8) =225
= 5^2 × 3^2
= 5^(5-3) × 3^(2×5 -8)
On comparing the both equations,
x =5
= 5^2 × 3^2
= 5^(5-3) × 3^(2×5 -8)
On comparing the both equations,
x =5

Answer:
The answer to this question is simple.
Step-by-step explanation:
as we know that 1515=225
therefore 5^x-3.3^2x-8=15^2.
so on solving we will get
15^(x-3)(2x-8)=15^2
so (x-3)(2x-8)=2
on further solving we will get an equation as x^2-7x-11=0
use shridhar acharya's formula then you will get the answer.
