What type of number is the sum of √ 2 and (3-√ 2) ?

Correct option is B

Given
First number = $$\sqrt{2}$$​​
Second number = $$3 - \sqrt{2}$$​​

Formula Used
Addition of real numbers.
A rational number can be expressed as a fraction of two integers.

Solution
Find the sum of the two given numbers:
Sum = $$\sqrt{2} + (3 - \sqrt{2})$$​​
Sum = $$\sqrt{2} - \sqrt{2} + 3$$​​
Sum = 3
Since 3 can be written as $$\frac{3}{1}$$​, it is an integer and therefore a rational number.

Final Answer
So the correct answer is (b)
