x^2 (4 - x); when x = 2
2^2 (4 - 2)
4^(4-2)
4^2
= 8
Your steps are not correct, 4^2 ≠ 8
should have been
= 4(2)
= 8
You got the right answer, but if I were to mark your work
I would deduct marks.
To find the value of the expression x^2 (4 - x) when x = 2, we can substitute the value of x into the expression and simplify.
First, we substitute x = 2 into the expression:
(2)^2 (4 - 2)
Now, we simplify each part of the expression individually:
(2)^2 equals 2 * 2, which is 4.
(4 - 2) equals 2.
So, the expression becomes:
4 * 2
Multiplying 4 by 2, we get the final answer as:
8
Therefore, when x = 2, the value of the expression x^2 (4 - x) is 8.
