Final Answer :
C
Explanation :
The logarithm of the square root of 60 can be simplified using logarithm properties: ln60=ln(601/2)=12ln60\ln \sqrt{60} = \ln (60^{1/2}) = \frac{1}{2} \ln 60ln60=ln(601/2)=21ln60 . Since 60=6×1060 = 6 \times 1060=6×10 , we can further simplify: 12(ln6+ln10)\frac{1}{2} (\ln 6 + \ln 10)21(ln6+ln10) . Substituting the given values, we get 12(1.7918+2.3026)=12(4.0944)=2.0472\frac{1}{2} (1.7918 + 2.3026) = \frac{1}{2} (4.0944) = 2.047221(1.7918+2.3026)=21(4.0944)=2.0472 .
