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.
