plese solve quest 4​

Answer 1

Answer:

- 281250

Step-by-step explanation:

25 ^ 3 - 75 ^ 3 + 50 ^ 3

= 25 ^ 3 + ( -75 ) ^ 3 + 50 ^ 3

We know that when for three numbers a, b and c,

a + b + c = 0,

a ^ 3 + b ^ 3 + c ^ 3 = 3abc

Since 25 + ( -75 ) + 50 = 0,

25 ^ 3 - 75 ^ 3 + 50 ^ 3

= 3 ( 25 ) ( -75 ) ( 50 )

= - 281250

25[1^3-3^3+2^3]

25[(2+1-3)^3}
