$\frac{a^{- 7} b^{8}}{a^{7} b^{- 2}}$

Step 1

Move $a^{- 7}$ to the denominator using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$\frac{b^{8}}{a^{7} b^{- 2} a^{7}}$

Step 2

Multiply $a^{7}$ by $a^{7}$ by adding the exponents.

Step 2.1

Move $a^{7}$ .

$\frac{b^{8}}{a^{7} a^{7} b^{- 2}}$

Step 2.2

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$\frac{b^{8}}{a^{7 + 7} b^{- 2}}$

Step 2.3

Add $7$ and $7$ .

$\frac{b^{8}}{a^{14} b^{- 2}}$

Step 3

Move $b^{- 2}$ to the numerator using the negative exponent rule $\frac{1}{b^{- n}} = b^{n}$ .

$\frac{b^{8} b^{2}}{a^{14}}$

Step 4

Multiply $b^{8}$ by $b^{2}$ by adding the exponents.
