Cho số thực dương a,b,c thỏa mãn a+b+c=3. Chứng minh rằng
a3+8≥2(ab+bc+ca)27+19.the fraction with numerator a squared and denominator b cubed plus 8 end fraction plus the fraction with numerator b squared and denominator c cubed plus 8 end fraction plus the fraction with numerator c squared and denominator a cubed plus 8 end fraction is greater than or equal to the fraction with numerator 2 open paren a b plus b c plus c a close paren and denominator 27 end fraction plus one-nineth pointa+b+c=0 and abc=-2. a^3+b^3+c^3=???
Find the values of a,b and c such that
\(\left(ax^2+bx+c\right)\left(x-1\right)=-5x^3+4x^2+3x-2\).
Answer: The values of a,b and c are ......... , respectively.
(used " ; " between the numbers)
How many 3 digit odd numbers abc such that a<b<(=)c and a+b+c=21
\(Cho:\frac{a+b}{c}=\frac{b+c}{a}=\frac{a+c}{b}\)
\(and........a\ne b\ne c........a,b,c\ne0\)
Tính \(A=\left(1+\frac{a}{b}\right)\left(1+\frac{b}{c}\right)\left(1+\frac{c}{a}\right)\)
