The degree of a monomial with several variables is the _____ of the exponents on those variables.

In all fractions, assume that no denominators are 0. Perform each division by simplifying each fraction. Write all answers without using negative or zero exponents. $$\frac{r^{3} s^{2}}{r s^{3}}$$

Multiply. $$\left(-5 t^{3}\right)\left(2 t^{4}\right)$$

The volume of the cube is \(s \cdot s \cdot s .\) Why do you think the symbol \(s^{3}\) is called "s cubed"?

Write each number in standard notation. $$9.76 \times 10^{-4}$$

Simplify each expression by writing it as an expression without negative exponents or parentheses. Assume no variables are $0. $$(2 y)^{-4}$$

Perform each division. Assume no division by \(0 .\) $$\frac{8 a^{2}+2 a-3}{2 a-1}$$

Identify the base and the exponent in each expression. $$-3 y^{6}$$

Simplify each expression by writing it as an expression without negative exponents or parentheses. Assume no variables are $0. $$(-4 z)^{-2}$$

Evaluate each expression. $$2\left(4^{3}+3^{2}\right)$$
