\[\large{\sqrt{28} = \sqrt{1}\sqrt{28} = \sqrt{1} \sqrt{4*7}}\]

SheldonEinstein Group TitleBest ResponseYou've already chosen the best response.3
So it will be \[\large{(\sqrt{1}) 2\sqrt{7} }\]

SheldonEinstein Group TitleBest ResponseYou've already chosen the best response.3
Now as we know that \[\large{\sqrt{1} = i (\textbf{IOTA})}\]

SheldonEinstein Group TitleBest ResponseYou've already chosen the best response.3
So we have answer : \(\large{ i \sqrt{28} }\)

SheldonEinstein Group TitleBest ResponseYou've already chosen the best response.3
Hence no need to simplify further.

Ah, yes. After a second look 2i√7 isn't an option.

Yeah, at first I thought the same and hence simplified it further but when saw the options again , I got to see the option i sqrt{28}...
