Question

2root2-root2
Don't know how do we get root2​

Answer 1

Answer:

$2 \sqrt{2} - \sqrt{2} \\ = \sqrt{2} (2 - 1) \\ = \sqrt{2}$

Answer 2

Step-by-step explanation:

2

$2 \sqrt{2} - \sqrt{2} = 2 \times 1.414 - 1.414 \\ = 2.82 - 1.414 = 1.414 = \sqrt{2}$

or

$2 \sqrt{2 } - \sqrt{2} = \sqrt{2} (2 - 1) = \sqrt{2} \times 1 = \sqrt{2}$
