If you mean in that exact order, then:

234^3=12,812,904

12,812,904/2=6406452

6406452^1/2=2,531.097 (As the above person said, ^1/2 is a square root.)

Therefore, if done in that exact order, then the answer is most likely Two million, five hundred thirty-one and Ninety-Seven ten-thousandths (2,531.097).

I am not going to do in OoO (Order of Operations; you know: PEMDAS).
