Question

HELP WHICH EXPRESSION

Answer 1

Answer:
(n^-3)^6

Explanation:
(n^-3)^6
=n^-18

We can use the law that a^-n=1/a^n to help us simplify n^-18.

n^-18
=1/n^18

I hope this helps! Please comment if you have any questions.

Answer 2

Answer:

$(n^{-3}) ^{6}$

Step-by-step explanation:

Using the rules of exponents

$(a^{m}) ^{n}$ ⇔ $a^{mn}$

$a^{-m}$ ⇔ $\frac{1}{a^{m} }$

Consider

$(n^{-3}) ^{6}$

= $n^{-3(6)}$

= $n^{-18}$

= $\frac{1}{n^{18} }$

The other 3 all simplify to $n^{18}$
