You know that 50^2 is 2500 (using 5^2 is 25 and add 0's) and that 60^2 is 3600 (using 6^2 is 36 and adding 0's), so the answer must be between 50 and 60. It is a bit closer to 60, so I would say around 56.
The estimate of the square root of 229 = ± 15 (actual square root is ± 15.132746).
The square root of 9 000 000 is 3000
Square root 64 and square root 81
The square root of 36 and the square root of 49.
The same way that you would for a rational number that is not a perfect square.
Expressed as a surd, the square root of 3000 is equal to 10 sqrt(30). Expressed as a decimal fraction rounded to two decimal places, the square root of 3000 is equal to ±54.77.
The estimate of the square root of 229 = ± 15 (actual square root is ± 15.132746).
You do not need to estimate it. It is exactly +13 or -13.
54.77 i think...

Square root of 64 and square root of 81, perhaps.
10*10 = 100 so I would not need to estimate it! The answer is -10 or +10
The square root of eight is in between the square root of 7 and the square root of 9, which equals 3.
the answer: 11
