Solve 5x^7/3x^2

$$\frac { 5 x ^ { 7 } } { 3 x ^ { 2 } }$$

Evaluate

$$\frac{5x^{5}}{3}$$

Steps for the Product of Two Exponentials

Use the rules of exponents to simplify the expression.

$$\left(5x^{7}\right)^{1}\times \frac{1}{3x^{2}}$$

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

$$5^{1}\left(x^{7}\right)^{1}\times \frac{1}{3}\times \frac{1}{x^{2}}$$

Use the Commutative Property of Multiplication.

$$5^{1}\times \frac{1}{3}\left(x^{7}\right)^{1}\times \frac{1}{x^{2}}$$

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

$$5^{1}\times \frac{1}{3}x^{7}x^{2\left(-1\right)}$$

Multiply 2 times -1.

$$5^{1}\times \frac{1}{3}x^{7}x^{-2}$$

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

$$5^{1}\times \frac{1}{3}x^{7-2}$$

Add the exponents 7 and -2.

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

Raise 5 to the power 1.

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

Multiply 5 times \frac{1}{3}.

$$\frac{5}{3}x^{5}$$

Steps for Quotient of Exponentials

Use the rules of exponents to simplify the expression.

$$\frac{5^{1}x^{7}}{3^{1}x^{2}}$$

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

$$\frac{5^{1}x^{7-2}}{3^{1}}$$

Subtract 2 from 7.

$$\frac{5^{1}x^{5}}{3^{1}}$$

Divide 5 by 3.

$$\frac{5}{3}x^{5}$$

Differentiate w.r.t. x

$$\frac{25x^{4}}{3}$$

Solution Steps

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

$$\frac{\mathrm{d}}{\mathrm{d}x}(\frac{5}{3}x^{7-2})$$

Do the arithmetic.

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

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}.

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

Do the arithmetic.

$$\frac{25}{3}x^{4}$$
