Find the square root of 28.

The square root of 28 is an irrational number, which means it cannot be expressed as a finite decimal or a fraction of integers. However, we can approximate it using decimal notation.

To find an approximation for the square root of 28, we can use a calculator or long division method. One common method is to use the prime factorization of the number to simplify the square root:

• 28 = 2^2 x 7
• √28 = √(2^2 x 7) = 2√7

Therefore, the square root of 28 is equal to 2 times the square root of 7. This is an exact expression for the square root of 28, but if we want a decimal approximation, we can use a calculator:

√28 ≈ 5.29150262… (rounded to 9 decimal places)
