This is a question i'm having trouble with.(adsbygoogle = window.adsbygoogle || []).push({});

Solve this equation for a

[tex]\iiint \,dz\,dy\,dx[/tex] = 2/7

I'm new to this code so i'll write the limits here.

the first integral sign is between 0 and 1

the second is between 0 and 4-a-x^2

the third is between 0 and 4-x^2-y

I've got to the third integral but this is what i've got to integrate

16-4a-8x^2+ax^2+x^4 - (16-8a-8x^2+2ax^2+a^2+x^4)

The bracketed part is all over 2, but again i don't know the code, sorry.

how would i go further with this? It's the bit where the bracket is over 2 that i'm having trouble with. Do i get rid of the brackets somehow or try to integrate the next part as it is? Any help would be much appreciated.

EDIT: I took the integral code from the LaTex thread, but the order should read dzdydx
