Question

$x = \frac{ \sqrt{2} }{2}$
the answer is ⤵️
$x = \frac{1}{ \sqrt{2} }$
but how ?
​

Answer 1

Step-by-step explanation:

1. x = -/2/2 x = -/2 / -/2 ×-/2 x= 1/-/2
2. I don't know how to use the sign of underroot

Answer 2

Answer:

Proved below

Step-by-step explanation:

$x = \frac{\sqrt{2} }{2}$

We can also write it as,

$x = \frac{\sqrt{2} }{\sqrt{2} * \sqrt[]{2} }$

As $\sqrt{2} * \sqrt[n]{2} = 2$

Now after cancelling $\sqrt{2}$

we get our final answer

i.e. $\frac{1}{\sqrt{2} }$
