Solve (2a^-1)^3

$$( 2 a ^ { - 1 } ) ^ { 3 }$$

Evaluate

$$\frac{8}{a^{3}}$$

Steps for Raising Power to Another Power

Use the rules of exponents to simplify the expression.

$$\left(2\times \frac{1}{a}\right)^{3}$$

To raise the product of two or more numbers to a power, raise each number to the power and take their product.

$$2^{3}\times \left(\frac{1}{a}\right)^{3}$$

Raise 2 to the power 3.

$$8\times \left(\frac{1}{a}\right)^{3}$$

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

$$8a^{-3}$$

Multiply -1 times 3.

$$8\times \frac{1}{a^{3}}$$

Steps for Raising Quotient to a Power

Use the rules of exponents to simplify the expression.

$$\left(\frac{2}{a^{1}}\right)^{3}$$

To raise the quotient of two numbers to a power, raise each number to the power and then divide.

$$\frac{2^{3}}{\left(a^{1}\right)^{3}}$$

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

$$\frac{8}{a^{3}}$$
