√6 .45

- 4

(45) 2 45

Square the 2, giving 4, write that underneath the 6, and subtract. Bring down the next pair of digits. Then double the number above the square root symbol line (highlighted), and write it down in parenthesis with an empty line next to it as shown. Next think what single-digit number something could go on the empty line so that forty-something times something would be less than or equal to 245.

45 x 5 = 225

46 x 6 = 276, so 5 works.
