(3.4)³ + (6.6)³ - (10)³
= (3.4)³ + (6.6)³ + (-10)³
if you know,
(a + b + c) = 0
then, a³ + b³ + c³ = 3abc
here we see ,
3.4 + 6.6 - 10 = 0
hence, (3.4)³ + (6.6)³ + (-10)³ = 3(3.4)(6.6)(-10)
(3.4)³ + (6.6)³ - (10)³ = 673.2
hence, answer is 673.2
= (3.4)³ + (6.6)³ + (-10)³
if you know,
(a + b + c) = 0
then, a³ + b³ + c³ = 3abc
here we see ,
3.4 + 6.6 - 10 = 0
hence, (3.4)³ + (6.6)³ + (-10)³ = 3(3.4)(6.6)(-10)
(3.4)³ + (6.6)³ - (10)³ = 673.2
hence, answer is 673.2
