Integrate

OpenStudy (anonymous):

\[\int\limits_{0}^{24} \sqrt{6x} dx\]

OpenStudy (tkhunny):

You should not be struggling with this. \(\int x^{1/2}\;dx\)?

OpenStudy (anonymous):

So far i got... \[\int\limits_{0}^{24} (6x)^{1/2} dx\]

OpenStudy (tkhunny):

Good. Why not just drag the constant out of the way? \(\sqrt{6}\int x^{1/2}\;dx\)

OpenStudy (anonymous):

Then I did.. \[6^{1/2}\int\limits_{0}^{24} x ^{1/2} dx\]

OpenStudy (tkhunny):

Then, what do we do with such exponents?

OpenStudy (anonymous):

I don't know...I got stuck in solving the rest of the parts

OpenStudy (tkhunny):

Pretty sure you;ve seen it. You're just not putting it together, \(\int x^{n}\;dx = \dfrac{x^{n+1}}{n+1} + C\) except where \(n = -1\).

OpenStudy (tkhunny):

It's not just integers. It's fractions, too.

OpenStudy (anonymous):

1/2+1 / 1/2+1?

OpenStudy (tkhunny):

1/2 + 1 = 3/2 \(\dfrac{x^{3/2}}{3/2} + C\)?
