Question
If x = 5√5 + √4 and y = 6√5 − √4 then x + y isSelect an answerA 11√5 − √4 B 11√5 + 2 C √5 + √4 D √5 + 11√4
Solution
The solution to the problem is as follows:
Given: x = 5√5 + √4 y = 6√5 - √4
We need to find x + y.
So, x + y = (5√5 + √4) + (6√5 - √4)
By combining like terms, we get:
x + y = 11√5
Therefore, none of the options A, B, C, D are correct. The correct answer is 11√5.
