To find 2 times the square root of 2, we start by calculating the square root of 2, which is an irrational number approximately equal to 1.414. When we multiply this by 2, we get:
2 × √2 ≈ 2 × 1.414 = 2.828.
Thus, 2 times the square root of 2 is approximately 2.828. This value is often encountered in various fields such as mathematics, physics, and engineering, especially in calculations involving right-angled triangles and other geometric figures.
