 It^, s not defined because infinite is not  a number, but lim_(x→∞) (x^0 )=1. It  happens because if x is a positive real  number, then x^0 =1.

$$\:\mathrm{It}^{,} \mathrm{s}\:\mathrm{not}\:\mathrm{defined}\:\mathrm{because}\:\mathrm{infinite}\:\mathrm{is}\:\mathrm{not} \\ $$$$\mathrm{a}\:\mathrm{number},\:\mathrm{but}\:{lim}_{{x}\rightarrow\infty} \left({x}^{\mathrm{0}} \right)=\mathrm{1}.\:\mathrm{It} \\ $$$$\mathrm{happens}\:\mathrm{because}\:\mathrm{if}\:{x}\:\mathrm{is}\:\mathrm{a}\:\mathrm{positive}\:\mathrm{real} \\ $$$$\mathrm{number},\:\mathrm{then}\:{x}^{\mathrm{0}} =\mathrm{1}. \\ $$
