Question

10. If x = [(2.25)³ + (3.07)³ + (2.13)³ - 3 x 2.25 x 3.07 x 2.13] and
y = (2.25)²+ (3.07)² + (2.13)² – (2.25) (3.07) – (3.07) (2.13) – (2.25) (2.13),
then
x/y = ​

Answer 1

x=[(2.25)ki power 3+(3.07)ki power 3 +(2.13)ki power 3-3×2.25×3.07×2.13]

=(2.25×2.25×2.25)+(3.07×3.07×3.07)+(2.13×2.13×2.13)-3×2.25×3.07×2.13)

=11.390625+28.934443+9.663597-
