Solve X+X=

$$X + X =$$

Differentiate w.r.t. X

$$2$$

Steps Using Definition of a Derivative

Combine X and X to get 2X.

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

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

$$2X^{1-1}$$

Subtract 1 from 1.

$$2X^{0}$$

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

$$2\times 1$$

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

$$2$$

Evaluate

$$2X$$

Solution Steps

Combine X and X to get 2X.
