<h3>Answer: Choice A</h3>

$\log_p N = b$ is not the same as $b^p = N$

The base of the log is p, while the base of the exponential is b. The two don't match. If it said $\log_p N = b \text{ is the same as } p^b = N$ then it would be a valid statement since the bases are both p.

-----------------

Extra info:

Choice B is a valid statement because Ln is a natural log with base 'e'

Choice C is valid as any square root is really something to the 1/2 power

Choice D is valid for similar reasons mentioned earlier
