Answer 2

Answer:

Corrected question:-

If x+y=12 and xy=27, find the value of x^3+y^3

3 .

Given that, x + y = 12 and xy =27

We know,

(x + y) ^ 3 = x ^ 3 + y ^ 3 + 3xy * (x + y)

Therefore,

12 ^ 3 = x ^ 3 + y ^ 3 + 3 * 27 * 12

1728 = x ^ 3 + y ^ 3 + 972

x ^ 3 + y ^ 3 = 1728 - 972 = 756

x ^ 3 + y ^ 3 = 756
