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

Step 1

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

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

Step 2

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

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