Solve 12x^7/3x^3=

$$\frac { 12 x ^ { 7 } } { 3 x ^ { 3 } } =$$

Evaluate

$$4x^{4}$$

Steps for the Product of Two Exponentials

Use the rules of exponents to simplify the expression.

$$\left(12x^{7}\right)^{1}\times \frac{1}{3x^{3}}$$

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

$$12^{1}\left(x^{7}\right)^{1}\times \frac{1}{3}\times \frac{1}{x^{3}}$$

Use the Commutative Property of Multiplication.

$$12^{1}\times \frac{1}{3}\left(x^{7}\right)^{1}\times \frac{1}{x^{3}}$$

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

$$12^{1}\times \frac{1}{3}x^{7}x^{3\left(-1\right)}$$

Multiply 3 times -1.

$$12^{1}\times \frac{1}{3}x^{7}x^{-3}$$

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

$$12^{1}\times \frac{1}{3}x^{7-3}$$

Add the exponents 7 and -3.

$$12^{1}\times \frac{1}{3}x^{4}$$

Raise 12 to the power 1.

$$12\times \frac{1}{3}x^{4}$$

Multiply 12 times \frac{1}{3}.

$$4x^{4}$$

Steps for Quotient of Exponentials

Use the rules of exponents to simplify the expression.

$$\frac{12^{1}x^{7}}{3^{1}x^{3}}$$

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

$$\frac{12^{1}x^{7-3}}{3^{1}}$$

Subtract 3 from 7.

$$\frac{12^{1}x^{4}}{3^{1}}$$

Divide 12 by 3.

$$4x^{4}$$

Differentiate w.r.t. x

$$16x^{3}$$

Solution Steps

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

$$\frac{\mathrm{d}}{\mathrm{d}x}(\frac{12}{3}x^{7-3})$$

Do the arithmetic.

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

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}.

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

Do the arithmetic.

$$16x^{3}$$
