How do you write fourteen and seven tenths squared in all three forms?

Not sure what the three forms are but here are some forms

note: pemdas, so parenthasees () are always first, work from inside the praenthasees to out

14 and 7/10 squared could mean:

(14 and 7/10) ^2

14 and [ (7/10) ^2]

14 and 7 / (10^2)
