Answer: Choice A


\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

Answer:

A.

Explanation:

A is incorrect. The definition of logarithms is that if
log_(a)b=c, then
a^c=b.

The variables are in the wrong place. The correct answer should be:


log_(p)N=b, p^b=N

B is correct since as
ln(x)=log_(e)(x). Thus,
e^y=x

C is correct because the square root of anything is simply that thing to the one-half power.

D is also correct as this is the definition of a logarithm.
