Which expression is equivalent to g−m ÷ gn?  g−m + n<br> g−m ⋅ n <br> g−m − n<br> g−m ÷ n
Sauron [17]
<h2>Answer:</h2>

The expression that is equivalent to the given expression is:

                       g^{-m-n}

<h2>Step-by-step explanation:</h2>

Two expression are said to be equivalent if by some simplification i.e. by some multiplication or division it could be represented in the same manner.

Here we are given a expression as:

                    g^{-m} ÷ g^n i.e.

             \dfrac{g^{-m}}{g^n}

We know that:

\dfrac{a^m}{a^n}=a^{m-n}

                 Hence, we get:

\dfrac{g^{-m}}{g^n}=g^{-m-n}
