Solve 3m^2-m^2=

$$3 m ^ { 2 } - m ^ { 2 } =$$

Differentiate w.r.t. m

$$4m$$

Steps Using Definition of a Derivative

Combine 3m^{2} and -m^{2} to get 2m^{2}.

$$\frac{\mathrm{d}}{\mathrm{d}m}(2m^{2})$$

The derivative of ax^{n} is nax^{n-1}.

$$2\times 2m^{2-1}$$

Multiply 2 times 2.

$$4m^{2-1}$$

Subtract 1 from 2.

$$4m^{1}$$

For any term t, t^{1}=t.

$$4m$$

Evaluate

$$2m^{2}$$

Solution Steps

Combine 3m^{2} and -m^{2} to get 2m^{2}.

$$2m^{2}$$
