sqrt ( 54 ) = sqrt ( 9 x 6 ) = 3 sqrt ( 6 )
The square root of 6 must be between the square root of 4 and 9 (which are equal to 2 and 3.)
Let's try 2.5, so 3 x 2.5 = 7.5
And: 7.5 x 7.5 = 56.25 (too high)
Lets try 2.4, so 3 x 2.4 = 7.2
And: 7.2 x 7.2 = 51.84 (too low)
Let's try 2.45, so 3 x 2.45 = 7.35
And: 7.35 x 7.35 = 54.0225 (close enough)
Therefore our answer is about 7.35.
Alternative ways to do this include calculus or just using a calculator.

The square root of 54 is ~7.35
Example: The square root of 54 The square root of 54 is not an integer, since 54 is not a perfect square. The square root of 54 will be between 7 and 8, since 54 is between 49 and 64. Since 54 is closer to 49 than it is to 64, the square root will be closer to 7 than 8. I'd estimate the square root of 54 to be approximately 7.35 The actual square root is plus or minus 7.3484692 To simplify a square root, search for any factors greater than one that are perfect squares. Since 54 = 9 x 6, the square root of 54 equals the square root of 9 x 6 equals the square root of 9 times the square root of 6. The square root of 9 is 3, so the square root of 54 simplified is 3 times the square root of 6.
