Exponent with \(1\):

For any number when it is rises to the power of 'one'\((1)\), it equals itself:

a^{1} = a .

where \( a ≠0\)

Example:

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

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

3. \(1^1 = 1\)

4. \((-1)^1\) \(= -1\)

5. \(0^1 = 0\)

Exponent with zero:

For any number when it is raised to the power of \(0\) it is always equals to the number \(1\):

a^{0} = 1 .

Example:

3^{0} = 1

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

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

1^{0} = 1

5. \((-1)^0 = 1\)
