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

4x=150
x=37.5 (not an integer)
If x=37 you get 37+38+39+40=154 and if x=38 you get 38+39+40+41=158[/tex]
