    ☆ Square root of 11 up to three decimal places.

    ☆ Using long division

    Additional Information :-

    Let us take some more examples :-

    1. Square root of 2 up to 3 decimal places

    [tex]\begin{gathered} \:\: \begin{array}{c|c} {\underline{\sf{}}}&{\underline{\sf{\:\:1.414 \:\:}}}\\ {\underline{\sf{1}}}& {\sf{\:\:2.000000 \:\:}} \\{\sf{}}& \underline{\sf{\:\: \: \: \: \: \: \: \: 1 \: \: \: \: \: \: \: \: \: \: \: \:\:}} \\ {\underline{\sf{24}}}& {\sf{\:\: \: \: \: \: 100 \: \: \: \: \: \: \: \:\:}} \\{\sf{}}& \underline{\sf{\:\: \: \: \: 96 \: \: \: \: \: \: \:\:}} \\ {\underline{\sf{281}}}& {\sf{\:\:400 \:\:}} \\{\sf{}}& \underline{\sf{\:\:281\:\:}} \\ {\underline{\sf{2824}}}& {\sf{\:\: \: \: \: \: \: 11900\:\:}} \\{\sf{}}& \underline{\sf{\:\: \: \: \: \: \: 11296\:\:}} \\ {\underline{\sf{}}}& {\sf{\: \: \: \: \: \: \: \: \: \: \: 604\:\:}}{\sf{}}&{\sf{\:\:\:\:}}\end{array}\end{gathered}[/tex]
