hey everyone i have some questions i need some help with. if you know the answer can u please help me
i need to differentiate these
1. x√(x_1)
2. 4x/(x^+x+3)^2
3. x/√(x_1)
i need someone to check my answers to these questions
a, 1/3√(x^4)
dy/dx = -1/3*4x^3*(x^4)^-4/3
= -4/3 x^-(5/3)
b, (1-4x)^3/2
answer -6(1_4x)^1/2
and lastly i need help with this question
determine the relationship between the normal to the curve y=y = x^3-2 x at x=1 and x=-1
pleassssse helppppp
thanx
