Let x1m+y1n+z1p = k.
So, x=km; y=kn; z=kp
xyz=1
→kmknkp=1
→k(m+n+p)=1
→m+n+p=0 if k≠1.
If k=1, m+n+p can have any value, including 0.
Sayantan Hazra even if k = 1, (m + n + p)can be zero........ :)

Km+n+p=11=10
So, m+n+p=0 or 1,
Sayan Sinha only when k=1, as I have already mentioned. ..
Samaroha Nandi It will be correct.
