$4 x^{- 2} + 3 x^{- 5}$

Step 1

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

$4 \frac{1}{x^{2}} + 3 x^{- 5}$

Step 2

Combine $4$ and $\frac{1}{x^{2}}$ .

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

Step 3

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

$\frac{4}{x^{2}} + 3 \frac{1}{x^{5}}$

Step 4

Combine $3$ and $\frac{1}{x^{5}}$ .

$\frac{4}{x^{2}} + \frac{3}{x^{5}}$
