Question

Shalu 3 power X equal to 5 power x - 2

Answer 1

Step-by-step explanation:

Step-by-step explanation:

3^x=5^x-2

Apply log on both sides

Iog3^x=log5^x-2

We know that loga^n = n log a

So,

X log 3= x-2 (log 5)

X log 3 =X (log 5) -2 (log 5)

X log 3 = X log 5 - 2 log 5

X log 3 - X log 5 = -2 log 5

-(X log 3 -X log 5) = 2 log 5

-X log 3 + X log 5 = 2 log 5

X(log 5-log 3) = 2log 5

Again,

Log a- log b=log a÷b

So,

X ( log 5/3)= 2 log 5

X (log 5/3)= log5^2

X (log 5/3) = log 25

X = log 25/log 5/3

That's it
