$12 x^{- \frac{1}{2}} + 7 x^{\frac{1}{2}} + x^{\frac{3}{2}}$

Etapa 1

Reescreva a expressão usando a regra do expoente negativo $b^{- n} = \frac{1}{b^{n}}$ .

$12 \frac{1}{x^{\frac{1}{2}}} + 7 x^{\frac{1}{2}} + x^{\frac{3}{2}}$

Etapa 2

Combine $12$ e $\frac{1}{x^{\frac{1}{2}}}$ .

$\frac{12}{x^{\frac{1}{2}}} + 7 x^{\frac{1}{2}} + x^{\frac{3}{2}}$
