Question

Suppose that n is a positive number and Log10 n = q. Which expression always equals the value of Log10 n^2?

Answer 1

2q

Answer:

solution given:

$log_{10} n=q$

now

$Log_{10 }n^2=?$

by using property of logarithms

$log_{a} n^p=p log_{a}n$

now

$Log_{10 }n^2=2 Log_{10 }n$

=2q

since $log_{10} n=q$
