    Pretty Simple.

    1.Integrate 3 separately.
    2.Take x common outside.
    3.That leaves x(raised to minus power half) + 6x(raised to power too ie. squared) The x that was taken common gets cancelled with the denominator.
    4. Answer- 3x + logx + 2x(cube) .....most probably.

    The answer may/ may not be correct(coz it's all mental math here ;)) , BUT I'm dead sure about the first 3 steps :)

    If you know even 1/4th of integration, you'd be able to make head and tail of what i said.

    Hmmm Thanks! I'll have to check this with my maths teacher though =D I'm pretty sure he'll call me an idiot for not knowing the answer to this though since we just went over it today! :eek: Out of all the other subjects, why did I pick maths? =[

    EASY QUESTION! I LOVE THIS SORTA PROBLEMS :D

    <> Integrate 3 .. which would be 3x
    +
    <> integrate (root x) / x which when simplified becomes = 1/(root x) which integrates to = 2.(root x)
    +
    <> integrate (6x^3)/x , which when simplified gives = 6.x^2...which integrates to = [6.(x^3)]/3 = 2.(x^3)
    +
    DONT FORGET TO ADD '+c'
    :)

    ps: too lazy to check all those steps up there...but the idea is correct
