The calculator already gives you a square root (or other root) with 8 or 10 significant digits, and does so quickly; there is no need to "estimate". However, you can round the result if you like.
For calculating simple fractions, i.e. that are only numbers and that do not include square roots in them, However, if you are going to use square roots, pi, sin, cos, tan and etc. The choice of calculator to use depends on how complex the fractions you are putting in are.
Rather than use your calculator to estimate numbers under a radical, simplify the radicals and leave them in the problem without plugging them into a calculator.
It is so easy if you use your calculator: ±7.937
You can use a calculator's square root function. If you want to calculate it yourself, you can try out the square of different numbers, until you get closer and closer to the target - in this case, 5184.

You type numbers in
