# Math Help - Derivative

1. ## Derivative

Would just like to see if I did this right..Thanks!
f(t)=2 √t^3 + 4/ √t- √2
=3t^3+4/ √t^1/2-2^1/2
=(t-1+2/t)
=(-1)+(2/t)+(t)
=(2/t)+(t)
=2(1/t)+(t)
=1-2/t^2

2. Before I can check it , I need to know what it is. Is this what you have?

$2\sqrt{t^3}+\frac{4}{\sqrt{t}}-\sqrt{2}$

4. OK. Here we go............

$\frac{d}{dx}2t^{5/2}+4t^{1/2}-2^{-1/2}=5t^{3/2}+2t^{-1/2}-0=5t^{3/2}+2t^{-1/2}$

any questions?
