If x + y = 13, then (x - 8)3 + (y - 5)3 is: |
2197 0 169 13 |
0 |
If x + y = 13, then (x - 8)3 + (y - 5)3 Subtract 13 from both the sides, x - 8 + y - 5 = 13 - 13 x - 8 + y - 5 = 0 now we can say x = 8 and y = 5 Put the values of x and y in the required equation, (x - 8)3 + (y - 5)3 = (8 - 8)3 + (5 - 5)3 (x - 8)3 + (y - 5)3 = 0 |
