If you have a non-scientific calculator you can use the Newton-Raphson method.
Let f(x) = x2 - 800, and f'(x) = 2x
[f'(x) is the derivative of f(x) but you do not need to know that to use the N-R method.]
Make a guess at the square root of 800, and call is x0.
Then calculate
xn+1 = xn - f(xn)/f'(xn) for n = 1, 2, 3, ...
Provided you made a reasonable choice for the starting point, the iteration will very quickly converge to the true answer. Even if it is not so good:
Suppose you start with x0 = 20 (a pretty poor choice since 202 is 400, which is nowhere near 800).
Even so, x3 = 2.843 is less than 1 in 24 thousand from the true value and x4 has an error of less than 1 in 30 billion.

What is the square root of 5 radical sign 800?
There is two ways to interpret "5 radical sign'. It can either mean: five times the square root of 800 leading to: √(5 × √800) ≈ 11.8921 or, if the five is small and raised slightly it is the fifth root of 800 and it leads to: √(fifth_root(800)) = (800^(1/5))^(1/2) = 800^(1/10) ≈ 1.9512

What number can you square that is bigger than 800 but smaller than 900?
The number you can square that is bigger than 800 but smaller than 900 is between the square roots of those two values. The square root of 800 is approximately 28.28, and the square root of 900 is 30. Therefore, any number between 29 and 30, such as 29.5, when squared, will yield a result between 800 and 900.
