x^(1/2) becomes (2/3)x^3/2) then multiplying in the two becomes...
(4/3)x^(3/2) which is correct yeh?
cool :D
ok another one. (1-4x)/(x*root*x)... i can't do the (4x)/(x^(3/2))
just a general interest thing for chemists.
i was shown this youtube video the other day:

Maths Integration Problem! HELP!
Homework Statement
ok maths problems is like this:
2.g. integrate (2x-1)/*square root x*
The Attempt at a Solution
ok. i split the equation up so that i am integrating 2x/*root x* - 1/*root x*
the 1/root x integrates to - 2x^(1/2) and the constant is...
