How to Calculate √150

The square root of 150 is approximately 12.2474487139. Since 150 is not a perfect square, its square root is an irrational number. We know that √144 = 12 and √169 = 13, so √150 falls between 12 and 13. The simplified radical form is 5√6. To estimate manually: start with 12.2, then refine using the Babylonian method — guess a value, divide 150 by it, average the result with your guess, and repeat.

The Babylonian Method (Step by Step)

  1. Start with an initial guess. Since √144 = 12 and √169 = 13, a good starting guess is 12.5.
  2. Divide 150 by your guess: 150 ÷ 12.5 = 12.0000
  3. Average the result with your guess: (12.5 + 12.0000) ÷ 2 = 12.250000
  4. Repeat with the new estimate until you reach the desired precision.
√150 ≈ 12.2474487139
