8(a+b)^(3)+27(b+c)

If a^(1/3)+b^(1/3)+c^(1/3)=0 show that (a+b+c)^(3)=27 abc

If a - 2b + 3c= 0 , state the value of a^(3) -8b^(3) + 27c^(3)

Factorise : 8a^(3) - 27b^(3)

1, 8, 27, 64, 124, 216, 343 (a) 8 (b) 27 (c) 64 (d) 124

If a,b,c are positive real numbers and sides of a triangle,then prove that (a+b+c)^(3)>=27(a+b-c)(b+c-a)(c+a-b)
