Solve 5.5u-2.7u

$$5.5 u - 2.7 u$$

Differentiate w.r.t. u

$$2.8$$

Steps Using Definition of a Derivative

Combine 5.5u and -2.7u to get 2.8u.

$$\frac{\mathrm{d}}{\mathrm{d}u}(2.8u)$$

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

$$2.8u^{1-1}$$

Subtract 1 from 1.

$$2.8u^{0}$$

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

$$2.8\times 1$$

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

$$2.8$$

Evaluate

$$\frac{14u}{5}$$

Solution Steps

Combine 5.5u and -2.7u to get 2.8u.

$$2.8u$$
