Square root of 1/2 = (1)/(square root of 2) = 1/1.4142 = 0.7071 Also Square root of 1/2 = Square root of 0.5 = 0.7071
square root of (x2 + 1) = no simplification (square root of x2) + 1 = x + 1
the square root of 1 is 1. The square root of -1 is j (if you are an engineer) or i (if you are a math geek)

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
sqrt(800) + sqrt(50) - sqrt(18) = 31.113 approximately.

20 times the square root of 2
Take the square root of 800, and the square root of 900. Look for an integer between the two.

The square root of 1/9 is 1/3 because the square root of 1 is 1 and the square root of 9 is 3.
Square root of 1/2 = (1)/(square root of 2) = 1/1.4142 = 0.7071 Also Square root of 1/2 = Square root of 0.5 = 0.7071
square root of (x2 + 1) = no simplification (square root of x2) + 1 = x + 1
a quarter is 1/4 and square root of 1/4 is square root (1/4)=square root of 1 divided by square root of 4 which is 1 divided by 2. So the answer is 1/2
x2+3i=0 so x2=-3i x=square root of (-3i)=square root (-3)square root (i) =i(square root(3)([1/(square root (2)](1+i) and i(square root(3)([-1/(square root (2)](1+i) You can multiply through by i if you want, but I left it since it shows you where the answer came from. Note: The square root of i is 1/square root 2(1+i) and -1/square root of 2 (1+i) to see this, try and square them!
