Evaluate (12)^3 + (-7)^3 + (-5)^3 using suitable identity

1.	Evaluate (12)^3 + (-7)^3 + (-5)^3 using suitable identity
Answer» $\text{[math]}$ given :- (12)³ + (-7)³ + (-5)³ using IDENTITY a³ + b³ + c³ = 3abc here, a = 12 b = -7 c = -5 therefore (12)³ + (-7)³ + (-5)³ = 3(12)(-7)(-5) = 3(420) = 1260 $\text{[math]}$

Answer»

$\text{[math]}$

given :- (12)³ + (-7)³ + (-5)³

using IDENTITY a³ + b³ + c³ = 3abc

here,

a = 12
b = -7
c = -5

therefore (12)³ + (-7)³ + (-5)³ = 3(12)(-7)(-5)

= 3(420)

= 1260

$\text{[math]}$
