club18 SG er.. its a level stuff. k. here it is.. i) differentiate x^x ii) hence or otherwise, differentiate x^x^x. help. thanks in advance.
Diehard_89 SG y=x^x ln both side lny = xlnx diferentiate both side (1/y)(dy/dx) = 1 + lnx make dy/dx the subject dy/dx = (1+lnx)/(1/y)
hisoka SG let y = x^x then take ln both sides. then using chain rule differentiate and solve for dy/dx. similarly for the other 2
