Hello everyone,

I have seen this rule among your study materials help, which i would like to thank you a lot for such effort .

Still i have a concern that i hope you correct me if i am wrong.

1) a/b+b/c+c/d+d/a=4 ?????????????
2)a^2*b+b^2*c+c^2a>=3abc

If we tried to blugg three negative values for a,b,c this won't be valied

Am i write and this is not a general rule or wut??

is there a particular reason why you would like to memorize this? I mean, I know that it could help on the calculation, but I wonder if it will take just as long as one trying to just solve the problem instead of trying to find the pattern. Just practise the fundamentals of fractions...
