Solve (k^5)^3

$$( k ^ { 5 } ) ^ { 3 }$$

Evaluate

$$k^{15}$$

Steps for Raising Power to Another Power

Use the rules of exponents to simplify the expression.

$$\left(k^{5}\right)^{3}$$

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

$$k^{5\times 3}$$

Multiply 5 times 3.

$$k^{15}$$

Differentiate w.r.t. k

$$15k^{14}$$

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).

$$3\left(k^{5}\right)^{3-1}\frac{\mathrm{d}}{\mathrm{d}k}(k^{5})$$

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}.

$$3\left(k^{5}\right)^{2}\times 5k^{5-1}$$

Simplify.

$$15k^{4}\left(k^{5}\right)^{2}$$
