You can have negative exponents anywhere. When they are in the denominator, they are equivalent to positive exponents in the numerator of a fraction.
why the exponents can not be negative
A negative exponent becomes positive in the reciprocal. So if you have a number a^x where x is negative, then, a^x = 1/(a^-x) and, since x is negative, -x is positive.
by doing reciprocal
They are the reciprocals of the positive exponents. Thus, x-a = 1/xa
Exponents that are NOT a negative exponent therefore they are mostly whole numbers kind of:)
Positive exponents: an = a*a*a*...*a where there are n (>0) lots of a. Negative exponents: a-n = 1/(a*a*a*...*a) where there are n (>0) lots of a.
Exactly that ... negative exponents. For example: 1000 = 103 That is a positive exponent. .001 = 10-3 That is a negative exponent. For positive exponents, you move the decimal place that many positions to the right, adding zeros as needed. For negative exponents, you move the decimal place that many positions to the LEFT, adding zeros as needed. And, the special case is this: 100 = 1.
They can be written as reciprocals with positive exponents. For example, 5-7 = (1/5)7

you make it into a fraction by puting whatever the negative exponent is attach to an pu that on the botttom of the fraction and leave a one on top
