The number is the base, and the little number above is the exponent.
4 goes into 11 twice
thats 2 for the whole number and for the fraction you have 3/4 left over
so 11/4=2 3/4
Substitute the value 350 in for your velocity:
350 = 20 * sq rt(273+t)
divide both by 20 --> 17.5 = sq rt(273 +t)
square both to cancel out the sq rt --> 306.25 = 273 +t
then just subtract 273 from both to get 33.25 = t
