Question 996103: Hi,
Here is the problem:
7.2x10%5E6 sqrt%289.3x10%5E3%29%281.2x10%5E5%29%2B%288.99x10%5E6%29%283.1x10%5E2%29
The square root extends to all four binomials and not just the first one, by the way. Also, the entire equation above is divided by %284.5x10%5E3%29%5E2.
Thanks so much to whoever helps!

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.
