Exponents usually refer to things like squared (x2) or cubed (x3), but can also be used to express fractions (division) and square roots. So division can be expressed as a power (exponent).
Let's use 4 as an example.
42 = 16
41/2 = 2 (this is the square root of 4)
4-2 = 1/16 = 1/(42) (negative indicates the reciprocal, so this becomes one OVER four squared, rather than 4 squared)
So if you are asked to find the exponent that is equivalent to 1/25, you could say it is 5-2 (OR 25-1)
Hope this helps.

To find the exponent in a division problem, you can use the rule that states, "When dividing like bases, subtract the exponents." For example, if you have x^5 divided by x^2, you subtract 2 from 5 to get x^3.
The answer to a division is the quotient
You subtract the exponent of the denominator from that of the numerator.
When dividing numbers with exponents, subtract the bottom exponent from the top exponent.
make a division problem and find the lowest number
P.E.M.D.A.S is how i remember it Parentheses Exponent Multiplication Division Addition Subtraction also, whichever comes first in the problem goes first, but this only works with multiplication and division and also addition and subtraction but only multiplication with division and addition with subtraction
