Simplify y^-3 <br><br> a.3/y<br> b.1/y^3<br> c.-3y<br> d.-1/y^3

nignag [31]

Answer:

b. $\frac{1}{y^3}$

Step-by-step explanation:

Here we are given $y^{-3}$ and are asked to simplify it. We are going to apply the law of exponents which says that

$a^{-n}=\frac{1}{a^n}$

Hence applying this rule in our problem we get, where a=y and n=3

$y^{-3}=\frac{1}{y^3}$

Hence our C) Option is correct
