Answer:
See below.
Explanation:
2−4÷2+23 =
= 2 - 2 + 23
= 0 + 23
= 23
This is the answer of the problem you posted, where 23 is the number twenty-three. 23 is not an answer choice, so perhaps 23 is not the number twenty-three, but rather 2 to the 3rd power, 2^3.
2−4÷2+2^3 =
= 2 - 2 + 8
= 0 + 8
= 8
8 is one of the choices.
