6x6x6x6x6 = 6⁵
7,776 is 6x6x6x6x6.
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.
53x53 in exponential form is: 532
The exponential form of 2x2x2x2x2 is: 25
50 in exponential form is: 5.0 × 101
8², that is the exponential form. :)
It is a prime so the exponential form is 49871
