Solve (m-8)+(8+m)

$$( m - 8 ) + ( 8 + m )$$

Evaluate

$$2m$$

Solution Steps

Add -8 and 8 to get 0.

$$m+m$$

Combine m and m to get 2m.

$$2m$$

Differentiate w.r.t. m

$$2$$

Steps Using Definition of a Derivative

Add -8 and 8 to get 0.

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

Combine m 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.

$$2$$
