27 is the value of the expression a³ + b³ + c³ - 3abc when terms are a = 2, b = 3 and c = 4.
Given that,
We have to find the value of the expression a³ + b³ + c³ - 3abc when a = 2, b = 3 and c = 4.
We know that,
Take the expression
a³ + b³ + c³ - 3abc
Substituting the values of a = 2, b = 3 and c = 4
(2)³ + (3)³ + (4)³ - 3(2)(3)(4)
By solving
8 + 27 + 64 - 72
99 - 72
27
Therefore, 27 is the value of the expression a³ + b³ + c³ - 3abc when a = 2, b = 3 and c = 4.
