Question

The rationalized answer of. 1/√2 is​

Answer 1

Rationalizing factor is the smallest number that is required to make the denominator a rational number.

Of course, sqrt(2) is not a rational number since it cannot be written as a fraction. To rationalize, we need the smallest number that will make sqrt(2) a rational number, which is itself. sqrt(2) * sqrt(2) is 2. We need to multiply sqrt(2) on the numerator too to make the number we’re multiplying equal to 1.

Answer: sqrt(2)/2
