Question

HOLA BRAINLY PEOPLE ! PROVE THAT log₇4 . log₅7 . log₂5 = 2

Answer 1

Hey Miss

Here's The Answer

------------------------------------------------

There are some very common used log property

==> logₓ(y) = log y/log x _______(1)

Now using this property (1) in L.H.S

==> log₇(4) . log₅(7) . log₂(5)

=> log(4)/log(7) . log(7)/log(5) . log(5)/log(2)

Cancelling, finally we get

=> log(4)/log(2)

We can also write it as

=> log₂(4)

=> log₂(2)²

=> 2 . log₂(2)

=> 2 . 1

=> 2

Hence Proved
