Question

log32187 = 7 can be expressed as _______A. 37 = 2187B. 32187 = 7C. 73 = 2187D. 72187 = 3

Answer 1

Recall the log to exponential rule:

$\begin{gathered} If \\ \log_aN=x \\ then \\ a^x=N \end{gathered}$

Therefore, we can express the log expression given to be:

$\log_32187=7$

in the exponential form as:

$3^7=2187$

OPTION A is correct.
