my question is...

OpenStudy (anonymous):

\[ \int\limits_{0}^{a}3x_{2}dx=8\]

OpenStudy (anonymous):

\[a^3=8\]

OpenStudy (anonymous):

no its not

OpenStudy (anonymous):

well what is question?

OpenStudy (anonymous):

find value of a

OpenStudy (anonymous):

do u know how to integrate 3x^2 ?

OpenStudy (anonymous):

ya

OpenStudy (anonymous):

well what is the answer of that integral?

OpenStudy (anonymous):

its 2 but i can't get this

OpenStudy (anonymous):

\[\int\limits_{0}^{a} 3 x^2 dx=8 \rightarrow a^3-0=8 \rightarrow a^3=8 \rightarrow a=2\]

OpenStudy (anonymous):

am i right?

OpenStudy (anonymous):

but how?

OpenStudy (anonymous):

well thats a simple integral \[ \huge \int\limits x^2 dx= \frac{x^3}{3}+C\]

OpenStudy (anonymous):
