Solve 8x^9/2x^2

$$\frac { 8 x ^ { 9 } } { 2 x ^ { 2 } }$$

Evaluate

$$4x^{7}$$

Steps for the Product of Two Exponentials

Use the rules of exponents to simplify the expression.

$$\left(8x^{9}\right)^{1}\times \frac{1}{2x^{2}}$$

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

$$8^{1}\left(x^{9}\right)^{1}\times \frac{1}{2}\times \frac{1}{x^{2}}$$

Use the Commutative Property of Multiplication.

$$8^{1}\times \frac{1}{2}\left(x^{9}\right)^{1}\times \frac{1}{x^{2}}$$

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

$$8^{1}\times \frac{1}{2}x^{9}x^{2\left(-1\right)}$$

Multiply 2 times -1.

$$8^{1}\times \frac{1}{2}x^{9}x^{-2}$$

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

$$8^{1}\times \frac{1}{2}x^{9-2}$$

Add the exponents 9 and -2.

$$8^{1}\times \frac{1}{2}x^{7}$$

Raise 8 to the power 1.

$$8\times \frac{1}{2}x^{7}$$

Multiply 8 times \frac{1}{2}.

$$4x^{7}$$

Steps for Quotient of Exponentials

Use the rules of exponents to simplify the expression.

$$\frac{8^{1}x^{9}}{2^{1}x^{2}}$$

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

$$\frac{8^{1}x^{9-2}}{2^{1}}$$

Subtract 2 from 9.

$$\frac{8^{1}x^{7}}{2^{1}}$$

Divide 8 by 2.

$$4x^{7}$$

Differentiate w.r.t. x

$$28x^{6}$$

Solution Steps

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

$$\frac{\mathrm{d}}{\mathrm{d}x}(\frac{8}{2}x^{9-2})$$

Do the arithmetic.

$$\frac{\mathrm{d}}{\mathrm{d}x}(4x^{7})$$

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}.

$$7\times 4x^{7-1}$$

Do the arithmetic.

$$28x^{6}$$
