Question

(х-3)3+х-х+4,при х=3;4;9;12;

Answer 1

(3-3)3+3-3+4=4

(4-3)3+4-4+4=7

(9-3)3+9-9+4=22

(12-3)3+12-12+4=31

Answer 2

To evaluate the expression (х-3)3+х-х+4 for different values of x, we'll simply substitute each value of x into the expression and calculate the result.

1. For x = 3: (3 - 3)^3 + 3 - 3 + 4 (0)^3 + 0 + 4 0 + 0 + 4 4

2. For x = 4: (4 - 3)^3 + 4 - 4 + 4 (1)^3 + 0 + 4 1 + 0 + 4 5

3. For x = 9: (9 - 3)^3 + 9 - 9 + 4 (6)^3 + 0 + 4 216 + 0 + 4 220

4. For x = 12: (12 - 3)^3 + 12 - 12 + 4 (9)^3 + 0 + 4 729 + 0 + 4 733

So, when x takes the values 3, 4, 9, and 12, the corresponding results are 4, 5, 220, and 733, respectively.
