Solve m^7/m^4

$$\frac { m ^ { 7 } } { m ^ { 4 } }$$

Evaluate

$$m^{3}$$

Steps Using Quotient of Powers Property

Use the rules of exponents to simplify the expression.

$$\frac{m^{7}}{m^{4}}$$

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

$$m^{7-4}$$

Subtract 4 from 7.

$$m^{3}$$

Differentiate w.r.t. m

$$3m^{2}$$

Solution Steps

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

$$\frac{\mathrm{d}}{\mathrm{d}m}(\frac{1}{1}m^{7-4})$$

Do the arithmetic.

$$\frac{\mathrm{d}}{\mathrm{d}m}(m^{3})$$

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}.

$$3m^{3-1}$$

Do the arithmetic.

$$3m^{2}$$
