Solve 20x^5/4x^2

$$\frac { 20 x ^ { 5 } } { 4 x ^ { 2 } }$$

Evaluate

$$5x^{3}$$

Steps for the Product of Two Exponentials

Use the rules of exponents to simplify the expression.

$$\left(20x^{5}\right)^{1}\times \frac{1}{4x^{2}}$$

To raise the product of two or more numbers to a power, raise each number to the power and take their product.

$$20^{1}\left(x^{5}\right)^{1}\times \frac{1}{4}\times \frac{1}{x^{2}}$$

Use the Commutative Property of Multiplication.

$$20^{1}\times \frac{1}{4}\left(x^{5}\right)^{1}\times \frac{1}{x^{2}}$$

To raise a power to another power, multiply the exponents.

$$20^{1}\times \frac{1}{4}x^{5}x^{2\left(-1\right)}$$

Multiply 2 times -1.

$$20^{1}\times \frac{1}{4}x^{5}x^{-2}$$

To multiply powers of the same base, add their exponents.

$$20^{1}\times \frac{1}{4}x^{5-2}$$

Add the exponents 5 and -2.

$$20^{1}\times \frac{1}{4}x^{3}$$

Raise 20 to the power 1.

$$20\times \frac{1}{4}x^{3}$$

Multiply 20 times \frac{1}{4}.

$$5x^{3}$$

Steps for Quotient of Exponentials

Use the rules of exponents to simplify the expression.

$$\frac{20^{1}x^{5}}{4^{1}x^{2}}$$

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

$$\frac{20^{1}x^{5-2}}{4^{1}}$$

Subtract 2 from 5.

$$\frac{20^{1}x^{3}}{4^{1}}$$

Divide 20 by 4.

$$5x^{3}$$

Differentiate w.r.t. x

$$15x^{2}$$

Solution Steps

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

$$\frac{\mathrm{d}}{\mathrm{d}x}(\frac{20}{4}x^{5-2})$$

Do the arithmetic.

$$\frac{\mathrm{d}}{\mathrm{d}x}(5x^{3})$$

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}.

$$3\times 5x^{3-1}$$

Do the arithmetic.

$$15x^{2}$$
