It may be hard understanding how the absolute value brackets vanished - comment if that's an issue

Hey, can you please help me with this question? integration and differenciation always confuse me.
Thank you

Thank you! How did you go from 2nd last to last line?

There's an error in the last line it seems; there should be a coefficient of 3 in front of the log

Hey! Don't stress about this, this exact integral used to be on the old reference sheet (table of integrals) but it isn't on there anymore, not assessable now ;D

I don't understand this law. If you had e^x^2 and substituted 1 in for x. If you times the powers together you get e^2 however if you bring the 2 to the front you get 2e and e^2 does not equal 2e.

Please add bracketing. It's ambiguous as to whether you mean \(e^{x^2}\) or \( \left(e^x\right)^2\)

Assuming you meant the latter though, I don't see how you can bring the 2 in front.
