Question

Cho a,b,c,d là các số thực dương. Chứng minh rằng (a^4)b + (b^4)c + (c^4)a + abc(a^3 + b^3 + c^3) >= (a+b+c)(3abc-1)

Answer 1

Answer:

Six rational numbers between −1/2 and 5/4 can be calculate as below

LCM of 2,4=4

−1/2=(−1×2)/(2×2)

We get,

=−2/4

Now, six rational numbers between −1/2 and 5/4 are as follows:

−1/4,0,1/4,2/4,3/4 and 4/4.
