Regardless of the base value of the step with the lever\(\ 1\) assumes a number equal to the given base:

a^{1} = a .

Example:

{(\frac{5}{8})}^{1} = \frac{5}{8}

{(- 14)}^{1} = - 14

\begin{array}{l} 1^{1} = 1 \\ {(- 1)}^{1} = - 1 \\ 0^{1} = 0 \end{array}

Important!

On the degree of the figure with the lever \(0\) accept the number \(1\):

a^{0} = 1 .

The exception is degree

0^{0}

that doesn't make any sense.

3^{0} = 1

{(7. 5)}^{0} = 1

{(- 8 \frac{1}{6})}^{0} = 1

\begin{array}{l} 1^{0} = 1 \\ {(- 1)}^{0} = 1 \end{array}

Important!

Numbers \(1,\) stepping up to any degree is \(1.\)

\begin{array}{l} 1^{n} = 1, n - any number . \\ 1^{1} = 1^{33} = 1^{199} = 1^{1000} = 1 \end{array}
