state, wheather it is a rational number or not
​

Answer 1

Answer:

NO.

Step-by-step explanation:

(2 + √2)² = (2)² + (2 × 2 × √2) + (√2)² = 4 + 4√2 + 2 = 6 + 4√2.

Since, √2 is an irrational number, so any other number which gets multiplied or added with it becomes an irrational number.

Therefore, (2 + √2)² is not a rational number.
