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
Answer:
You can look for these:
Step-by-step explanation:
The factors of the equation:
For example, if multiplication, the factors 2x2=4
if addition, the addends 2 + 2= 4
So just look for the numbers before the equal sign and any key words in the problem.
Hope this helps!
Thus, the final answers are 1 and -1/8.
The answer c, because they got 9 out of 15 flips being heads. This probability is 0.6. The other answers are not accurate.
