-----> Any number at all with a 0 exponent is 1; anything with a -ve exponent means "1 over" i.e. 5^-1 means 1/5, 23^-4 means 1/23^4 etc.
----->A number to the power of zero is always 1
A number to the power of a negative number such as 2^-4 is always the reciprocal to the power of 4 so 2^-4 is in fact (1/2) ^4 = 1/2^4
3^-3/4 is (1/3)^3/4
(4/9)^-3/5 is (9/4)^3/5
--->Any number with a zero exponent is equal to 1. A number n to the -x is equal to 1/(n^x)
To simplify a negative exponent expression , I attached an example it is easier that way :)
Hope that helps.xoxo
