Question

why a^0 =1?
a can be any number. ​

Answer 1

we have to prove so let a = 25

therefore 25^2÷25^2

therefore 25*25/25*25

25 will be cancelled by 25 and 25 will be cancelled by 25

so there will be only 1

the answer will be one

according to the exponent theorem

25^2÷25^2

25^2-2

25^0

=1

so LHS=RHS
