Solve x^8/x^-3=

$$\frac { x ^ { 8 } } { x ^ { - 3 } } =$$

Differentiate w.r.t. x

$$11x^{10}$$

Solution Steps

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

$$\frac{\mathrm{d}}{\mathrm{d}x}(\frac{1}{1}x^{8-\left(-3\right)})$$

Do the arithmetic.

$$\frac{\mathrm{d}}{\mathrm{d}x}(x^{11})$$

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}.

$$11x^{11-1}$$

Do the arithmetic.

$$11x^{10}$$

Evaluate

$$x^{11}$$

Solution Steps

To divide powers of the same base, subtract the denominator's exponent from the numerator's exponent. Subtract -3 from 8 to get 11.

$$x^{11}$$
