Answer

False

Work Step by Step

We are given the following expression: $(\log{x})^2\stackrel{?}{=}\log{x^2}$ Recall the power property of logarithms (pg. 462): $\log_b{m^n}=n\log_b{m}$ We apply this property to the right side of our expression: $(\log{x})^2\stackrel{?}{=}2\log{x}$ $\log{x}\times\log{x}\ne\log{x}+\log{x}$ We see that the statement mistakes addition for multiplication and is therefore false.
