When dividing two powers that have the same nonzero base, keep the base and SUBTRACT the exponents. This is called the quotient of powers exponent law.

Multiple Choice

Simplify the expression.

$\frac{\left(-3.1\right)^7}{\left(-3.1\right)^5}$

$\left(-3.1\right)^2$

$\left(-3.1\right)^{12}$

$\left(-3.1\right)^{35}$
