The value of 0.051 × 0.051 × 0.051 +

Home » Aptitude » Simplification » Question

The value of 0.051 × 0.051 × 0.051 + 0.041 × 0.041 × 0.041 is :
0.051 × 0.051 − 0.051 × 0.041 + 0.041 × 0.041

Let 0.051 = x and 0.041 = y

∴ The given expression =	x³ + y³
	x² − xy + y²

=	(x + y)(x² − xy + y²)
	x² − xy + y²

= x + y = 0.051 + 0.041
= 0.092

The value of	0.051 × 0.051 × 0.051 + 0.041 × 0.041 × 0.041	is :
	0.051 × 0.051 − 0.051 × 0.041 + 0.041 × 0.041
