Question

what is the derivative:

t^3-4t^2+5t(square t) -5

I can get 3t^2-8t (not sure what to do with 5t (square t)

Answer 1

by (square t) do you mean t^2?

Answer 2

2t\[\sqrt{t}\]


I can't type them next to one another

Answer 3

it is 2t (square t)

Answer 4

5t sqrt(t) = 5t t^(1/2) = 5t^(3/2)

Answer 5

5*(3/2) t^((3-2)/2) =

(15/2) t^(1/2) = 15sqrt(t)/2

Answer 6

it tends to be easier to work with "exponents" than with radicals.... so turn all the radicals into the appropriate "exponent" and solve from there :)

Answer 7

thanks
