Usually referred to as exponential notation, this form of numerical expression lets you move the decimal point in an equation to simplify the writing and remove the following or leading zeros. To multiply exponential notation you add the exponents and to divide the two expressions you subtract the exponents all as a base of 10.
2,000 = 2 x 10 to the third power. (10^3)
2,000,000,000 divided by 2,000 = 2 x 10^9 - 2 x 10^3 = 2 x 10^6

Oh, that's a big number! In standard form, we would write it as 10^52 since there are 52 zeros after the 1. In exponential form, it would be written as 1 x 10^52. Just imagine all the possibilities and beauty that can come from such a vast number!
If the question is, Is y = x4 an exponential function ? then the answer is no.An exponential function is one where the variable appears as an exponent.So, y = 4x is an exponential function.
anything to the power of 0 is 1 except for 0. 0^0 is an indeterminate form. one way to demonstrate this is x^a/x^a = x^(a-a) which can be rewritten as 1=x^0. since e is not 0 e^0=1. this only works to numbers not infinity.
It means the number form of the exponent.
