∫[( 5/x〗 + 6x2 – e^x + x^(1/2))dx

OpenStudy (anonymous):

evaluate

OpenStudy (anonymous):

one sec let me re write equation

OpenStudy (anonymous):

∫[( 5/x〗+ 6x^[2] - e ^[x] + x^(1/2))dx

OpenStudy (anonymous):

= ln|5/x| + 2x^3 - e^x + (2/3)*x^(3/2) + C

OpenStudy (anonymous):

how did you get 2x^3

OpenStudy (anonymous):

the integral of 6x^2 is (6x^3)/3 which simplifies to 2x^3

OpenStudy (angela210793):

@agdgdgdgwngo shouldn't it b 5ln|x|? O.o

OpenStudy (lalaly):

5lnx +2x^3 - e^x +2/3 x^3/2

OpenStudy (anonymous):

right lalay the first one should be 5ln|x|

OpenStudy (anonymous):

i am confused so which one is the right integral

OpenStudy (anonymous):

lalay's one

OpenStudy (anonymous):

lalay is right

OpenStudy (anonymous):

isnt there a + c at the end

OpenStudy (anonymous):

the antiderivative of 1/x is ln and then you mulltiply that constant back in. And yes there is a +C at the end

OpenStudy (lalaly):

yeh forgot the +c ...

OpenStudy (anonymous):

cool
