Question

Prove 3log2+log5=log40

Answer 1

Answer:

heya mate there's your answer

let us take LHS:-

3log2+log5 = log2^3 +log5

(mlogn=logn^m)

=log8+log5

=log(8×5)

(loga+logb=log(ab))

=log40.

=RHS

SO,3log2+log5=log40

Answer 2

Answer:

its true bacause 8 x 5 = 40 and 3log2 =8 while log5 =5

prove in the below steps

Step-by-step explanation:

first  let us take LHS:-

3log2+log5 = log2^3 +log5

                                               :.>  fromula(mlogn=logn^m)

=log8+log5

=log(8×5)

(loga+logb=log(ab))

=log40.
