Solve a_{1}(5)

$$a _ { 1 } ( 5 )$$

Differentiate w.r.t. a_1

$$5$$

Steps Using Definition of a Derivative

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

$$5a_{1}^{1-1}$$

Subtract 1 from 1.

$$5a_{1}^{0}$$

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

$$5\times 1$$

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

$$5$$

Evaluate

$$5a_{1}$$
