Question

rationalise the denominator 1 divided by root 2
$1 \div \sqrt{2 = }$
​

Answer 1

Solution:

Here, we have to rationalize the number $\sf\frac{1}{√2}$.

To rationalise the number firstly we have to multiply the same value which is in denominator.

$\sf \implies \: \frac{1}{ \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} }$

Now,multiply.

$\sf \implies \: \frac{ \sqrt{2} }{( { \sqrt{2}) }^{2} } \\ \\ \sf \implies \: \frac{ \sqrt{2} }{2}$

Hence, after rationalize the answer become √2/2.
