If n = 4, all of the following expressions are equivalent except _____.

16

Answer 1

\[\frac{1}{n^2}=\frac{1}{4^2}=\frac{1}{16}\]and \[n^{-2}=\frac{1}{n^2}\]

So what answer do you think?

Answer 2

1 over n^2?

Answer 3

No...the last 3 options are equivalent...the first is not.

Answer 4

so 16?

Answer 5

Yes...since 1/16 (which the other options equate to) does not equal 16
