4. The Real Number System

Rewrite the expression with NO negative exponents.

$y^{-8}$

Simplify the expression.

$\frac{y^{27}}{y^9}$

Simplify the expression.

$(-4t{)}^0,t\ne 0$

Rewrite the expression with NO negative exponents.

${10}^{-1}$

Simplify each expression using the product rule if possible.

${12}^3\cdot {12}^9$

Simplify the expression with NO negative exponents.

$\frac{3^{-4}}{5^{-2}}$

Simplify each expression, but don’t evaluate.

${\left(4^{15}\right)}^3$

Use the quotient rule to rewrite each expression, then simplify.

$\frac{9x^2{y}^8}{3x{y}^2}$
