Question

if 5^x-3,3^2x-8=228 ,then find the value of x​

Answer 1

Answer:

5^x-3.  3^2x-8 = 225

                = 3 × 75  

                = 3 × 3 × 25  

                = 3 × 3 × 5 × 5

∴ 5^x-3.  3^2x-8 = 5^2 × 3^2

Comparing both the sides we get

x − 3 = 2

⇒ x = 5

((You can compare even the other one also. The result will be same))
