When you multiply a number by itself several times, the exponent form is a much easier way of writing this product down than a self-repeating series of factors.
Let's say you need to multiply the number a by itself 13 times. Instead of typing a*a*a*a*a*a*a*a*a*a*a*a*a, you simply put it in exponential form, noting it down like this: a13. This way of writing the product give exactly the same information, yet is it time saving, space saving and easier to read.

How do you use an exponent to represent a number such as 16
x2y4z6-121 Use the difference of two squares to factorise:- (xy2z3-11)(xy2z3+11)
Yes, 25 CAN BE and exponent. Any number can be and exponent
The exponent is a characteristic of a number. A measurement unit does not have an exponent. Since a metre is a measurement unit, it does not have an exponent.
you get an exponent when you multiply EXAMPLE 10x10x10=1000 that is an exponent NO DONT THINK THAT IF THE EXPONENT IS 3 YOU MULTIPLY IT BY 3 NO WAY JOSE
