i tried using the quotient rule .. but that didn't work

so find derivative of sqrt(6)*t^7?

also the power rule... so what's next?

make it first look like sqrt(6)*t^7

notice that sqrt (6) is constant. and t^7 is the variable you are worrying about.

can i not use the power rule then quotient rule?

katherine.ok Group TitleBest ResponseYou've already chosen the best response.1
because this is simply exponent derivative,you not need to worry about quotient rule , power rule.

\[\large f(t) = \frac{\sqrt{6}}{t^7} = \sqrt{6}t^{7}\]\[\large f'(t) = \sqrt{6} \cdot 7 t^{71} \]\[\large f'(t) = 7 \sqrt{6}t^{8}\]\[\large f'(t) = \frac{7\sqrt{6}}{t^8}\]

power rule and quotient rule is applicable in more complicated setting where you have f(x)*g(x) .

ohhhhhhh. right right. this is just simple derivative

You should know that \[\large \frac{d}{dx} x^{n} =\frac{nx^{n1}}{n1}\]
