7.2 x 10^6*{[11.16 x 10^8+27.87 x 10^8]}^1/2
I will divide 7.2 x 10^6/20.25 x 10^6
That is 0.355556
The four binomials are sqrt (39.03 x 10^8)=6.2474 x 10^4
Those two are multiplied by 0.3555556=22212.97
====
Quick estimation.
The radical is over 40 x 10^8= about 6 x10^4.
That times the first term is about 43 x 10^10
Divide by the number given, which is about 20 x 10^6
should be a little more than 2 x 10^4.
