A binary operation ? is defined on the set of real numbers R, by x?y = \(\sqrt{x+y - \frac{xy}{4}}\), where x, yER. Find the value of 4?3
- A. 16
- B. 8
- C. 4
- D. 2
Correct Answer: D. 2
Explanation
x?y = \(\sqrt{x+y - \frac{xy}{4}}\)
4?3 = \(\sqrt{4+3 - \frac{4*3}{4}}\)
= \(\sqrt{4+3-3}\)
= \(\sqrt{4}\)
= 2.
