Answer
Rewrite: $y=\frac{10}{3}x^{-3}$
Differentiate: $(\frac{10}{3})(-3)(x^{-3-1})$
Simplify: $-\frac{10}{x^4}$
Work Step by Step
Rewrite: factor out the constant and reverse the sign of the exponent to get the expression into the numerator.
Differentiate: Using the Constant Multiple Rule and the Power Rule, differentiate to get $(\frac{10}{3})(-3)(x^{-3-1})$.
Simplify: Multiply out the constants and take the expression back to the denominator to get rid of the negative exponent.
