Answer:
Any number raised to zero is one.
Examples:
[tex]4^{0} = 1\\\\178^0=1\\\\15^0 = 1[/tex]
Any number raised to a negative integer is 1 over that exponential term without the negative exponent.
Examples:
[tex]5^{-1} = \frac{1}{5}\\\\324^{-13}=\frac{1}{324^{13}}\\\\17^{-6} = \frac{1}{17^{6}}[/tex]
