Question

Difference between $\sf \sqrt[2]{2} \ and \ \sqrt{2}$​

Answer 1

Answer:

The square root of 2 or root 2 is represented using the square root symbol √ and written as √2 whose value is 1.414. This value is widely used in

Answer 2

Step-by-step explanation:

Mathematically, Root 2 is denoted as √2.

So Root 2 + Root 2,

√2 + √2 = 2√2

If we consider the approx. value of √2 = 1.4142

Then 2√2 = 1.4142 x 2 = 2.8284 (approx.)

Note that √2 is an irrational number.

- - - - -

On the other hand,

root2 × root 2

√2 * √2 = 2

Since √2 is nothing but square root of 2.

- - - - -

Therefore,

the difference between root 2 + root 2 and root2 × root 2

2√2 - 2 = 2.8284 - 2 = 0.8284 (approx.)
