Question
Classify the given pair of surds into like surd and unlike surd.
`19 sqrt 12 , 6 sqrt 3`
Solution
`19 sqrt 12, 6 sqrt 3`
`19 sqrt12 = 19 xx sqrt(4xx3)`
`= 19 xx sqrt4 xx sqrt3`
`= 19 xx 2sqrt3`
`= 38sqrt3`
Here, the order of `38sqrt3` and `6sqrt 3` is same and their radicands are also same.
`19 sqrt 12, 6 sqrt 3` are like surds.
