Step-by-step explanation:
Firstly, we'll try to simplify the integrand. By hint 1, we see that:
Simplifying the integrand gives us:
Next, by hint 2, we observe that:
So this tells us to make the substitution: 
Doing so gives us:
, which should be trivial.
The answer is 7 hope this helps
Answer:
x^8-y^8
Step-by-step explanation:
7x - 3x = 24
The 7x and the 3x are both like terms, so they can be combined. 7 - 3 is 4, so the equation turns into
4x = 24
Now, you want to get the x alone, so you divide both sides by 4 because it is the opposite of multiplication. 24 divided by 4 is 6, so
x = 6
