$40 a^{- 2} + 59 a^{- 1} - 8$

Step 1

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$40 \frac{1}{a^{2}} + 59 a^{- 1} - 8$

Step 2

Combine $40$ and $\frac{1}{a^{2}}$ .

$\frac{40}{a^{2}} + 59 a^{- 1} - 8$

Step 3

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$\frac{40}{a^{2}} + 59 \frac{1}{a} - 8$

Step 4

Combine $59$ and $\frac{1}{a}$ .

$\frac{40}{a^{2}} + \frac{59}{a} - 8$

Step 5

Reorder terms.

$\frac{59}{a} + \frac{40}{a^{2}} - 8$
