Exponents, Advanced!

Simplify:  $\left(-2k\right)^3$  

Simplify:     $6m^3\ \cdot\ 8m^4$  

According to exponent rules, when you multiply exponential expressions with the same base, you _______ the exponents.

Anything raised to the power of zero is:

Simplify the following:     $\left(\frac{2x^3}{3x}\right)^{-2}$  

 $\left(\frac{3x^{-3}y^7}{x^6y^{-4}}\right)^{-3}$  

According to exponent rules, when we raise an exponential expression to a power we ____________ the exponents.

The exponent rules state that when exponential expressions with the same base are divided we ______ the exponents.

 $7x^2\ \cdot\ 2x^{-3\cdot}\cdot\ x^8$  

 $\frac{-40x^3y^4}{-8x^3y}$
