Find the value of \( \Large log_{10}8100 \)
A) \( \Large 2+2log_{10}9 \)
B) \( \Large 2log_{10}9 \)
C) \( \Large 2+log_{10}9 \)
D) \( \Large 2 \left(1+3log_{10}9\right) \)
Correct Answer:
A) \( \Large 2+2log_{10}9 \)
Description for Correct answer:
\( \Large log_{10}8100=log_{10}81+log_{10}100 \)
=\( \Large log_{10}9^{2}+log_{10}10^{2} \)
=\( \Large 2log_{10}9+2log_{10}10 \)
=\( \Large 2log_{10}9+2 \)
=\( \Large 2+2log_{10}9 \)
