I started with AC + A'BD' + A'BE + A'C'DE
I got to AC + A'(BD' + BE + C'DE)
Then to (A + BD' + BE + C'DE)(A' + C)
Then to (A + C'DE + B(D' + E)) (A' + C)
Then to (A + B + C'DE)(A + C'DE + D' + E)(A' + C)

What can I do from here?

I've had these up but no one has been able to help me with the following. The first of the three seems to be the trickiest...

Use Integration by parts to evaluate the integrals:

[IntSign](ln(4x))^2 dx

[IntSign]x^(9)cos(x^5) dx

Evaluate the following:

[IntSgn]sin^3(4x)cos^8(4x) dx

Ok here is the problem:

One night, the King couldnt sleep, so he went down into the kitchen, where he found a bowl of mangoes. Being hungry, he took 1/6 of the mangoes. Later that same night, the queen was hungry and found the mangoes and took 1/5 of what the king had left. Still later, the first prince awoke, went to the kitchen, and ate 1/4 of the remaining mangoes. Even later, his brother, the second prince, ate 1/3 of what was left. Finally, the third prince ate 1/2 of what was left, leaving only three mangoes for the servants. How many mangoes were originally in the bowl?
Someone please help me figure this out!!
Thanks!

Use the product rule to find the derivative.

f(x) = (x^2 - 2x + 2)(2x^3 - x^2 + 5)


if you could explain this problem step by step it would help thank you.
