$$( 1 a ) ^ { 4 }$$

Evaluate

$$a^{4}$$

Solution Steps

Expand \left(1a\right)^{4}.

$$1^{4}a^{4}$$

Calculate 1 to the power of 4 and get 1.

$$1a^{4}$$

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

$$a^{4}$$

Differentiate w.r.t. a

$$4a^{3}$$

Steps Using Definition of a Derivative

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

$$4a^{4-1}$$

Subtract 1 from 4.

$$4a^{3}$$
