Solve m+2m-m=

$$m + 2 m - m =$$

Evaluate

$$2m$$

Solution Steps

Combine m and 2m to get 3m.

$$3m-m$$

Combine 3m and -m to get 2m.

$$2m$$

Differentiate w.r.t. m

$$2$$

Steps Using Definition of a Derivative

Combine m and 2m to get 3m.

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

Combine 3m and -m to get 2m.

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

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

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

Subtract 1 from 1.

$$2m^{0}$$

For any term t except 0, t^{0}=1.

$$2\times 1$$

For any term t, t\times 1=t and 1t=t.

$$2$$
