Question

3 power x =5 power x-2 give answer fast

Answer 1

Answer:

Step-by-step explanation:

3^x = 5^(x-2)

Applying log on both the sides

log 3^x = log 5^(x-2)

【log n^a = a log n】

x log 3 = (x-2) log 5

x log 3 = x log 5 - 2log 5

2log 5 = x log 5 - x log 3

Taking x common

2 log 5 = x ( log 5-3)

2 log 5 / log 2 = x

【 x log n = log n ^ x】

log 5^2 / log 2 = x

log 25 / log 2 = x

Hope it helps!
