Question

$$\frac { 3 ^ { - 5 } \times 3 ^ { 7 } } { 3 ^ { - 2 } }$$

Evaluate

$81$

Solution Steps

To multiply powers of the same base, add their exponents. Add $-5$ and $7$ to get $2$.

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

To divide powers of the same base, subtract the denominator's exponent from the numerator's exponent. Subtract $-2$ from $2$ to get $4$.

$$3^{4}$$

Calculate $3$ to the power of $4$ and get $81$.

$$81$$

Factor

$3^{4}$
