Simplifying 909^0 and n0n^0 Using the Zero Exponent

Apply the Zero Exponent rule to simplify two expressions — one with a numerical base and one with a variable base.

90=19^0 = 1: The base is 99, which is nonzero. By the Zero Exponent rule, any nonzero number raised to the zero power equals 11. Therefore 90=19^0 = 1.

n0=1n^0 = 1: The base is the variable nn. Assuming n0n \neq 0, the same rule applies: n0=1n^0 = 1.

In both parts, the zero exponent collapses the expression to 11 regardless of what the base is — whether it is a specific number like 99 or an unspecified variable like nn. The only requirement is that the base must not be zero.
