 \sqrt{18.49} = \sqrt{ \frac{1849}{100} } =  \frac{43}{10} = 4.3
 \sqrt{0.1849} = \sqrt{ \frac{1849}{10000} } = \frac{43}{100} = 0.43
 \sqrt{0.001849} =  \sqrt{ \frac{1849}{1000000} }= \frac{43}{1000}  =0.043
Therefore,  \sqrt{18.49} + \sqrt{0.1849} + \sqrt{0.001849} = 4.3+0.43+0.043
=4.773

Now, firstly, we have  \sqrt{18.49} , we will first express it as a fraction, i.e.  \frac{1849}{100} . Take its square root :  \frac{ \sqrt{1849} }{ \sqrt{100} } , then you'll get the fraction as  \frac{43}{10} = 4.3
