Solve frac{u^frac{2{3}}}{u^frac{3{5}}}

$$\frac { u ^ { \frac { 2 } { 3 } } } { u ^ { \frac { 3 } { 5 } } }$$

Evaluate

$$\sqrt[15]{u}$$

Steps Using Quotient of Powers Property

Use the rules of exponents to simplify the expression.

$$\frac{u^{\frac{2}{3}}}{u^{\frac{3}{5}}}$$

To divide powers of the same base, subtract the denominator's exponent from the numerator's exponent.

$$u^{\frac{2}{3}-\frac{3}{5}}$$

Subtract \frac{3}{5} from \frac{2}{3} by finding a common denominator and subtracting the numerators. Then reduce the fraction to lowest terms if possible.

$$\sqrt[15]{u}$$

Differentiate w.r.t. u

$$\frac{1}{15u^{\frac{14}{15}}}$$

Solution Steps

To divide powers of the same base, subtract the denominator's exponent from the numerator's exponent.

$$\frac{\mathrm{d}}{\mathrm{d}u}(\frac{1}{1}u^{\frac{2}{3}-\frac{3}{5}})$$

Do the arithmetic.

$$\frac{\mathrm{d}}{\mathrm{d}u}(\sqrt[15]{u})$$

The derivative of a polynomial is the sum of the derivatives of its terms. The derivative of a constant term is 0. The derivative of ax^{n} is nax^{n-1}.

$$\frac{1}{15}u^{\frac{1}{15}-1}$$

Do the arithmetic.

$$\frac{1}{15}u^{-\frac{14}{15}}$$
