@Reaper534 can u help?

okay

Well, can you integrate
\[\Large \int x ^{-\frac43}=\color{red}?\]

yes i get -3/3sqrt(x)

This
\[\Large \frac{-3}{3\sqrt{x}}\]?

yes!

Or this
\[\Large \frac{-3}{\sqrt[3]x}\]

the second one

lol... it's cube root, not 3sqrt
because \(\Large3\sqrt x\) means something entirely different, ok?

Okay

Okay, so, we have...
\[\Large \int\limits_1^b x^{-\frac43}=\left.\frac{-3}{\sqrt[3]x}\right]_1^b\]

Can you evaluate this bit?

i think

Well then, what do you get?

hmm i'm working on it

eh...i'm getting a wrong answer :/

ohhhh okay

so i plug in b and 1 into that then subtract?

Yes... but that's not the end yet, just plug in for now, and tell me what you get :)

okay so -3/3sqrt(b) - -3/3sqrt(1)

yes

okay

So... evaluating the limit...?

umm i get 3? :/

That's right!

ohh okay lol

so thats the final answer?

okay thanks

No problem :)
