Solve frac{a^frac{22{12}}}{a^frac{7{6}}}

$$\frac { a ^ { \frac { 22 } { 12 } } } { a ^ { \frac { 7 } { 6 } } }$$

Evaluate

$$a^{\frac{2}{3}}$$

Steps Using Quotient of Powers Property

Use the rules of exponents to simplify the expression.

$$\frac{a^{\frac{11}{6}}}{a^{\frac{7}{6}}}$$

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

$$a^{\frac{11}{6}-\frac{7}{6}}$$

Subtract \frac{7}{6} from \frac{11}{6} by finding a common denominator and subtracting the numerators. Then reduce the fraction to lowest terms if possible.

$$a^{\frac{2}{3}}$$

Differentiate w.r.t. a

$$\frac{2}{3\sqrt[3]{a}}$$

Solution Steps

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

$$\frac{\mathrm{d}}{\mathrm{d}a}(\frac{1}{1}a^{\frac{11}{6}-\frac{7}{6}})$$

Do the arithmetic.

$$\frac{\mathrm{d}}{\mathrm{d}a}(a^{\frac{2}{3}})$$

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}.

$$\frac{2}{3}a^{\frac{2}{3}-1}$$

Do the arithmetic.

$$\frac{2}{3}a^{-\frac{1}{3}}$$
