Here are the degrees of prime numbers that are often used:

Example:

Calculate

7^{2} - 2^{5}

The first step is always exponentiation.

\begin{array}{l} 7^{2} = 49; \\ 2^{5} = 32 . \end{array}

Substituting the found values, we obtain:

7^{2} - 2^{5} = 49 - 32 = 17

Consider examples of degrees with negative bases:

\begin{array}{l} {(- 3)}^{2} = (- 3) \cdot (- 3) = 9; \\ {(- 3)}^{3} = (- 3) \cdot (- 3) \cdot (- 3) = - 27; \\ {(- 3)}^{4} = (- 3) \cdot (- 3) \cdot (- 3) \cdot (- 3) = 81 . \end{array}

Important!

An even degree of a negative number is positive; an odd one is negative.
