is that all over x^9?
OpenStudy (anonymous):
yes
OpenStudy (anonymous):
the i would suggest simplifying it first , like for the first term it would be 2x^9/x^9=2
OpenStudy (anonymous):
ok
OpenStudy (anonymous):
so, your good, or you still have some doubts

lagrange did good on this, so what is the question that remains?
OpenStudy (anonymous):
what
OpenStudy (amistre64):
recall the power rule for integrations\[\int x^ndx=\frac{1}{n+1}x^{n+1}\]
thats the only thing that would be needed to finish it up
OpenStudy (anonymous):
i really dont know how to start the problem

1/(x^n)=x^(-n)
OpenStudy (amistre64):
you start it with algebra .....
simplify the integrand
OpenStudy (inkyvoyd):
THe power rul for integration still applies, unless n=-1
OpenStudy (anonymous):
so 2x^10/x^10?
OpenStudy (inkyvoyd):
Remember that you can seperate each term with the distributive property.

how
OpenStudy (inkyvoyd):
(2x^9-6x^2+3)/(x^9)
=(2x^9)/(x^9) -(6x^2)/(x^9) +3/(x^9)
OpenStudy (inkyvoyd):
Just pre algebra, my friend.
