Question

value of (√23+√11)(√23-√11)​

Answer 1

Answer:

answer is 12

Step-by-step explanation:

this question is in the form of (a+b) (a-b) = (a^2 - b^2)

hence after putting the values we get

(root 23 + root 11) (root 23 - root 11) = (root 23 ^2 - root 11^2)

therefore if a square root is squared it will give you a number not in root

hence root 23 = 23 and root 11 = 11

therefore 23 - 11 = 12
