Question

# , where and is

- a negative integer
- a prime integer
- a positive integer
- an even–natural

Hint:

### In this question, we have to find the. Where the value of A and B is given A = √1 + √2 + √5- √10And B=. To solve this question, solve B, rationalize it find the value B then find the .

## The correct answer is: a positive integer

In this question, we have to find the . Here Solve first B. In B, rationalize it means multiply it denominator by sign change in both numerator and denominator
