Describe how a power with a zero exponent and a power with a negative exponent can be simplified?

-----> 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

A exponent with a 0 equals itself. ex.) 6^0=0
A negative power can be simplified by 6^-1=6/-1

Iknow one of the answers is a and maybe b but not 100% sure about b
