Without a square root key, there is no simple way to find square roots. The best method is probably the Newton Raphson iteration.
If you want to find the square root of k, define f(x) = x^2 – k. Then finding the square root of k is equivalent to solving f(x) = 0.
Let f’(x) = 2x. This is the derivative of f(x) but you do not need to know that to use the N-R method.
Start with x0 as the first guess. Then let xn+1 = xn - f(xn)/f’(xn) for n = 0, 1, 2, …
Provided you made a reasonable choice for the starting point, the iteration will very quickly converge to the true answer. It works even if your first guess is not so good:
Suppose you want the square root of 7 and you start with x0 = 5 (a pretty poor choice since 5^2 is 25, which is nowhere near 7).
Even so, x3 = 2.2362512515, which is less than 0.01% from the true value. Finally, remember that the negative value is also a square root.

Use a calculator. Most will allow you to find 70(1/4) Or find the square root of the square root of 70.
The same way you find the square root of any number. The fastest way would be to type 225, followed by the square root key, in a calculator.
The square root of 2304 is 48 by means of a calculator
The square root of 0.375 is approximately 0.612. To find the square root of a decimal number, you can use a calculator or long division method. In this case, you would take the square root of 375 (which is 19.364) and then divide by 10 to get the final answer of approximately 0.612.
first you get a calculator. then you put in 5000. after that you press the square root button(the one with the open square) and your answer should be...70.710678 but if you round it to the nearest tenth then it would be..70.7! now im absolutely sure that im right cuz i used a calculator to check my answer!
