## Calculus 10th Edition

Rewrite: $4\sqrt x$ Differentiate $4(\frac{1}{2\sqrt x})$ Simplify: $\frac{2}{\sqrt x}$
Simplify: Use the Index Rule $(\frac{x^a}{x^b}=x^{a-b})$ to get $4x^{\frac{3}{2}-1}=4\sqrt x$ Differentiate: Using The Constant Multiple Rule and the Power Rule, differentiate the expression to get $4(\frac{1}{2\sqrt x})$. Simplify: Multiply out the constants.
