calculus - Compute: int10fracx4+1x6+1dx



I'm trying to compute: 10x4+1x6+1dx.



I tried to change x4 into t2 or t, but it didn't work for me.



Any suggestions?




Thanks!


Answer



Edited Here is a much simpler version of the previous answer.



10x4+1x6+1dx=10x4x2+1x6+1dx+10x2x6+1dx



After canceling the first fraction, and subbing y=x3 in the second we get:



10x4+1x6+1dx=101x2+1dx+13101y2+1dy=π4+π12=π3.




P.S. Thanks to Zarrax for pointing the stupid mistakes I did...
