Question

Using square root table, find the square root
4192 

Answer 1

\[\sqrt{4192} = \sqrt{2 \times 2 \times 2 \times 2 \times 2 \times 131}\]
\[ = 2 \times 2\sqrt{2} \times \sqrt{131}\]

 

The square root of 131 is not listed in the table. Hence, we have to apply long division to find it. 

Substituting the values:
            =  \[2 \times 2 \times 11 . 4455\] 

 (using the table to find \[\sqrt{2}\] )

    = 64.75
