Which expression is equivalent to log3(x + 4)?

solmaris [256]

ANSWER

The third option is the correct answer

$log3(x + 4) = log(3) + log(x + 4)$

EXPLANATION

The expression given to us is

$log3(x + 4) = log(3) + log(x + 4)$

This logarithmic expression is of the form

$log(A \times B)$

So we use the multiplication law of logarithm which is given by

$log(A \times B) = log( A ) + log( B )$

We therefore set

$A = 3$

$B = x + 4$

The given expression now becomes,

$log3(x + 4) = log(3) + log(x + 4)$
