How to Calculate √1000

The square root of 1000 is approximately 31.6227766017. Since 1000 is not a perfect square, its square root is an irrational number. We know that √961 = 31 and √1024 = 32, so √1000 falls between 31 and 32. The simplified radical form is 10√10. To estimate manually: start with 31.6, then refine using the Babylonian method — guess a value, divide 1000 by it, average the result with your guess, and repeat.

The Babylonian Method (Step by Step)

  1. Start with an initial guess. Since √961 = 31 and √1024 = 32, a good starting guess is 31.5.
  2. Divide 1000 by your guess: 1000 ÷ 31.5 = 31.7460
  3. Average the result with your guess: (31.5 + 31.7460) ÷ 2 = 31.623016
  4. Repeat with the new estimate until you reach the desired precision.
√1000 ≈ 31.6227766017
