How to Calculate √32

The square root of 32 is approximately 5.6568542495. Since 32 is not a perfect square, its square root is an irrational number. We know that √25 = 5 and √36 = 6, so √32 falls between 5 and 6. The simplified radical form is 4√2. To estimate manually: start with 5.6, then refine using the Babylonian method — guess a value, divide 32 by it, average the result with your guess, and repeat.

The Babylonian Method (Step by Step)

  1. Start with an initial guess. Since √25 = 5 and √36 = 6, a good starting guess is 5.5.
  2. Divide 32 by your guess: 32 ÷ 5.5 = 5.8182
  3. Average the result with your guess: (5.5 + 5.8182) ÷ 2 = 5.659091
  4. Repeat with the new estimate until you reach the desired precision.
√32 ≈ 5.6568542495
