Answer 2

Step-by-step explanation:

let the example be.....2√6.45.....

Then continue in this way.....

• 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 = 22546 x 6 = 276, so 5 works.
• Write 5 on top of line. Calculate 5 x 45, write that below 245, subtract, bring down the next pair of digits (in this case the decimal digits 00).
• Then double the number above the line (25), and write the doubled number (50) in parenthesis with an empty line next to it as indicated:
• Think what single digit number something could go on the empty line so that five hundred-something times something would be less than or equal to 2000. 503 x 3 = 1509504 x 4 = 2016, so 3 works.
• Calculate 3 x 503, write that below 2000, subtract, bring down the next digits.
• Then double the 'number' 253 which is above the line (ignoring the decimal point), and write the doubled number 506 in parenthesis with an empty line next to it as indicated:
• 5068 x 8 = 405445069 x 9 = 45621, which is less than 49100, so 9 works...
