Exponential form is a number with an exponent in it. I'll give you an example. 65 (6x6x6x6x6) 34 (3x3x3x3) An exponent is the smaller floating number to the left of the 6 or 3 in the examples. An exponent or power of a number means to multiply the number be itself that many times, that's how 65 is also 6x6x6x6x6, 6 times itself 5 times. Great.
It is already in standard form.
5 as a power of 6^5 = 7776
