The definition of the answer looks like magic.
It's needs to be cross-checked 😑

.:.(2{14}*3{21})/(7{24}*2{98})
simplifying,we would arrive at- (2*{7}*{2}*3*{7}*{3})/(7*{3}*{2}*{4}*2*{7}*{7}*{2})
.:. Those with similar roots would cancel out,leaving out 3/(7*{4}*{2}) = 3/7*2*{2} =3/14{2}. Rationalizing,we get (3/14{2})*({2}/{2}) .:.giving us 3{2}/14*2 =3{2}/28.

i got a different thing 😃
my school I got (3√2)/28 as my answer ..
if possible shoot a video on this and explain clearly.
