Question

prove that log5040=4log 2+ 2log 3+log5+log7

Answer 1

Hello dear user!!!


Here is your answer goes like this :


====================================================



Your question :





Answer:

Given,

Let us prove RHS

= 4 log 2 + 2 log 3 + log 5 + log 7

= log (2)⁴ + log (3)²+ log 5 + log 7

= log ( 16 x 9 x 5 x 7)

= log 5040

Let us take LHS:

Given log5040

=log(16×9×5×7)

=log 16+log 9+log 5+ log 7

=log 2⁴+log 3²+log 5+log 7

=4 log 2+2 log 3+ log 5+ log 7

(Log a^n=n log a)

HENCE, LHS=RHS.....



The answer has been explained......
