Question

if a+b+c = 0
abc = 25
find the minimum value for $a^{3} + b^{3} + c^{3}$

Answer 1

a³+b³+c³-3abc=(a+b+c)(a²+b²+c²-ab-bc-ca); (a+b+c)=0; a³+b³+c³-3abc=0; a³+b³+c³=3abc=3×25=75; Please mark the answer as brainliest.

Answer 2

Answer:

we have a formula , if a + b + c = 0

a^3 + b^3 + c^3 = 3abc

given abc = 25

so , a^3+ b^3 + c^3 = 3(25) = 75
