Question

at I: The value of (25)³ +(-16)³+(-9)³ is 10800​

Answer 1

Answer:

we have a formula for it

a3+b3+c3=3abc

3×25×-16×-9=10800

Answer 2

Answer:

- 25 + 16 + 9 =0

let x = -25

y = 16

z = 9

x y z = 0

x^3 + y^3 + z^3 - 3xyz

=(x + y + z)(x^2 + y^2 + z^2 -xy - yz -

zx)

If x + y + z =0, then x^3 + y^3 + z^3 = 3xyz

(- 25)^3 + (16)^3 + (9)^3 = 3 × (-25) × (16) × (9)

= (-75) × (144)

= - 10800
