Solve sum4^2

$$\sum 4 ^ { 2 }$$

Differentiate w.r.t. Σ

$$16$$

Steps Using Definition of a Derivative

Calculate 4 to the power of 2 and get 16.

$$\frac{\mathrm{d}}{\mathrm{d}Σ}(Σ\times 16)$$

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

$$16Σ^{1-1}$$

Subtract 1 from 1.

$$16Σ^{0}$$

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

$$16\times 1$$

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

$$16$$

Evaluate

$$16Σ$$

Solution Steps
