since cscB = 1/sinB
cscB = 1/(5√2/5√3)
= 5√3/5√2 = √3/√2
cscB = 1/(5√2/5√3)
= 5√3/5√2 = √3/√2

They obviously rationalized by answer
√3/√2
= √3/√2 *(√2/√2) = √6/2
Since the original given information was not rationalized I logically assumed they would supply the answer in the same way.
You could have used your calculator to evaluate my answer, then checked with of the given ones match it.
