# Simplify: $$\Large log_{10}2500$$

 A) 2 B) 1 C) 3 D) 4

 B) 1

Description for Correct answer:
Simplify: $$\Large log_{10}2500$$

$$\Large log_{10}2500$$ = $$\Large log_{10} \left(25 \times 100\right)$$

=$$\Large log_{10}25+log_{10}100$$

=$$\Large log_{10}5^{2}+log_{10}10^{2}$$

=$$\Large 2log_{10}5+2log_{10}10$$

=$$\Large 2log_{10}5+2$$

Therefore, $$\Large \left[ log_{10}10=1 \right]$$
