-----> A<span>ny 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.
</span>----->A number to the power of zero is always 1
<span>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 </span>
<span>3^-3/4 is (1/3)^3/4 </span>
<span>(4/9)^-3/5 is (9/4)^3/5
</span>
--->Any number with a zero exponent is equal to 1. A number n to the -x is equal to 1/(n^x)<span>
To simplify a negative exponent expression , I attached an example it is easier that way :)
Hope that helps.xoxo

SA = 4 * (pi) * r^2......solving for (pi)
divide both sides by 4r^2
SA / (4r^2) = (pi)

Answer:
x = 3
Step-by-step explanation:
8(x+2) = 40
8x + 16 = 40
8x = 24
x = 3
The answer is to that is 100
