Answer:
20%
Step-by-step explanation:
3 out of 15 is the same as 3/15 = 1/5. 1/5 is the same as 20%
Difference of 2 perfec squares is
(a^2)-(b^2)
if the exponents are both even and the coeficient (the number in front) are perfect squares, then it is difference t 2 perfect squares
first one
8 is not perfect square
2nd one
(4e^4)^2-(9g^2)^2
third
25 is odd, so it cannot be split up into 2 nice numbers
4th
(11m^9)^2-(3n^5)^2
The correct answer is (20,-50)
We are given (xy)^(-3).
This leads to 1/(xy)^3.
You see, going from the top to the bottom alters the sign of the exponent to its opposite.
