Answer 2

Hie mate!

We have to rationalize 1/(√3)

So,

To do that, we have to get a important thing in our mind that when we rationalize anything we only gotta change the irrational number present downside or at the denominator,

if your denominator is a rational number than you have perfectly rationalized it.

It doesn't matter if your numerator is a rational number or not, your deno. should be a rational to be called rationalised.

Now, when we try to rationalize any fraction/rational number we have to multiply the number (any number you are taking) to both the nume. and the deno.

Now,

1/(√3)

To rationalize it, i am multiplying (√3) by both nume. and deno. so that the deno. becomes rational.

1 · (√3) / (√3) · (√3)

(√3 times √3 = 3)

So, by this

we got

⇒(√3) / 3

Now, √3/3 is perfectly rationalized.
