Question

Rewrite the following equation in logarithmic form using a base 10 logarithm.Use log for the base 10 logarithma = 10^K

Answer 1

we have the expression

$a=10^k$

Applying log both sides

$\begin{gathered} \log _{10}a=\log _{10}10^k \\ \log _{10}a=k\cdot\log _{10}10^{} \\ \log _{10}a=k\cdot1 \\ k=\log _{10}a^{} \end{gathered}$
