★Square Root of 12/20

• The square root of 12/20 can either mean the square root of (12/20) or the square root of 12 divided by 20.
• These are different problems with potentially different answers.

Calculate √12/20

The square root of (12/20) is the same as the square root of 12 divided by the square root of 20. You can divide the fraction inside the radical before or after you calculate the square root. The result will be the same.

Here we first calculate the square root of the numerator and the square root of the denominator separately, and then we divide the two:

• √12√20 ≈ 3.46414.4721

Alternatively, we first divide 12 by 20 and then do the square root of the quotient:

• √12/20 = √0.6 ≈ 0.7746
