Evaluate the expression $7^{3}$ .

Short Answer

Expert verified

The expression $7^{3}$ can be written as 343.

Step by step solution

Step 1. Apply the formula for breaking integral powers.

For any real number ‘a’ with the integer power ‘n’ of the form $a^{n}$ can be expressed as:

$a^{n} = a \times a \times a \times .................. n times.$

Step 2. Example of breaking integral powers.

The expression $3^{4}$ can be written as $3^{4} = 3 \times 3 \times 3 \times 3 (4times)$ which is 81.

Step 3. DESCRIPTION OF STEP.

The given expression $7^{3}$ can be written as:

$\begin{array}{l} 7^{3} = 7 \times 7 \times 7 (3times) \\ \Rightarrow 7^{3} = 343 \end{array}$
