Solve (w^4)^2=

$$( w ^ { 4 } ) ^ { 2 } =$$

Evaluate

$$w^{8}$$

Steps for Raising Power to Another Power

Use the rules of exponents to simplify the expression.

$$\left(w^{4}\right)^{2}$$

To raise a power to another power, multiply the exponents.

$$w^{4\times 2}$$

Multiply 4 times 2.

$$w^{8}$$

Differentiate w.r.t. w

$$8w^{7}$$

Steps Using Chain Rule

If F is the composition of two differentiable functions f\left(u\right) and u=g\left(x\right), that is, if F\left(x\right)=f\left(g\left(x\right)\right), then the derivative of F is the derivative of f with respect to u times the derivative of g with respect to x, that is, \frac{\mathrm{d}}{\mathrm{d}x}(F)\left(x\right)=\frac{\mathrm{d}}{\mathrm{d}x}(f)\left(g\left(x\right)\right)\frac{\mathrm{d}}{\mathrm{d}x}(g)\left(x\right).

$$2\left(w^{4}\right)^{2-1}\frac{\mathrm{d}}{\mathrm{d}w}(w^{4})$$

The derivative of a polynomial is the sum of the derivatives of its terms. The derivative of a constant term is 0. The derivative of ax^{n} is nax^{n-1}.

$$2\left(w^{4}\right)^{1}\times 4w^{4-1}$$

Simplify.

$$8w^{3}\left(w^{4}\right)^{1}$$

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

$$8w^{3}w^{4}$$
