Question

root 2+root 2 into root 2- root 2

Answer 1

Step-by-step explanation:

What is the difference between root 2 + root 2 and root2 × root 2?

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.)

Hope that solves the query.

Phew! You should try asking your mathematics teacher too. :P
