The main property is as follow
(A^p)^q=A^pxq
so only Sam's work is correct because
(8^4)^5 x(7^3)^9=(8^4x5)x(7^3x9)=8^20x 7^27
There's nothing preventing us from computing one integral at a time:



Expand the integrand completely:

Then

Answer:
D. (bottom right)
Step-by-step explanation:
If there is a line where y = x, that means that y and x can both equal 1, 2, 3, -1, -2, -3, etc. They are just always the same. This line, then, would pass through (just for example) (-4, -4) and (4, 4). If you reflect the pink figure across that line, you will get the blue figure. Hope this helps!

Answer:
-3 < x ≤ 13
Step-by-step explanation:
