Question
Express $ \log_{10}2 + 1$ in the form of $ \log_{10}x .$
✓
Answer
$\log_{10}2 + 1= \log_{10}2 + \log_{10}10 ....[ \because \log_{10}10 = 1 ]$
$= \log_{10}2 \times 10 ....[ \log_am + \log_an = \log_amn ]$
$= \log_{10}20.$
$= \log_{10}2 \times 10 ....[ \log_am + \log_an = \log_amn ]$
$= \log_{10}20.$
