a = 5^-2 as an ordinary number has to be just a number, not raised to any power, not a fraction, but a simple plain number. So 5^-2 = 1/5^2 => 1/25 = 0.04. That's it. A Decimal number is also an ordinary number. And, dont mind that guy; it's not a stupid question. Alright then, take care.

5^-2 Means 1/(5^2)=1/25= 0.04 Is The Answer!

Do you know what a number is? That is an ordinary number. Learn what math is before you ask stupid questions on here.

5^-2 = 1/(5^2) = 1/25 = 0.04 <<<

Do you mean an "ordinary" or an "ordinal" number?
