## anonymous 5 years ago 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)

1. anonymous

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

2. anonymous

2t$\sqrt{t}$ I can't type them next to one another

3. anonymous

it is 2t (square t)

4. amistre64

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

5. amistre64

5*(3/2) t^((3-2)/2) = (15/2) t^(1/2) = 15sqrt(t)/2

6. amistre64

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 :)

thanks
