Write Using Negative Exponents 8/3x+7x^5

$\frac{8}{3} x + 7 x^{5}$

Move $x^{1}$ in $\frac{\frac{8}{3} x}{1}$ to the denominator and change the exponent from positive to negative.

$\frac{\frac{8}{3}}{x^{- 1}}$

Move $x^{5}$ in $\frac{7 x^{5}}{1}$ to the denominator and change the exponent from positive to negative.

$\frac{7}{x^{- 5}}$

Rewrite the expression with the negative exponents.

$\frac{\frac{8}{3}}{x^{- 1}} + \frac{7}{x^{- 5}}$
