Question

In the following equation, find which variables x, y, z etc. represent rational or irrational number:

w2 = 27

Solution

Given that w2 = 27

Now we have to find the value of w

`rArrw=sqrt27`

`rArrw=sqrt(3xx3xx3)`

`rArr w=3sqrt3`

So it is an irrational number

  Is there an error in this question or solution?
