Solve (a^3)^4

$$( a ^ { 3 } ) ^ { 4 }$$

Evaluate

$$a^{12}$$

Steps for Raising Power to Another Power

Use the rules of exponents to simplify the expression.

$$\left(a^{3}\right)^{4}$$

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

$$a^{3\times 4}$$

Multiply 3 times 4.

$$a^{12}$$

Differentiate w.r.t. a

$$12a^{11}$$

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).

$$4\left(a^{3}\right)^{4-1}\frac{\mathrm{d}}{\mathrm{d}a}(a^{3})$$

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}.

$$4\left(a^{3}\right)^{3}\times 3a^{3-1}$$

Simplify.

$$12a^{2}\left(a^{3}\right)^{3}$$
