square root(20) over 36 = 0.124225999
No.
Yes because it can't be expressed as an exact fraction
If it's just the square root of x, and that is over 20, you're looking for x=100. Here's why: 1/2 is one half. What number is 1/2 of 20? 10, right? What number has a square root that equals 10? 100! So~ the square root of 100 is 10. 10 out of 20 is equal to 1 out of 2.
It is 2*sqrt(5).

It is 2*sqrt(5).
Because the Square Root of negative 1 = i (The imaginary square root of negative 1.) and where if the square root of one number and of another number are multiplied together, the answer is equal to the square root of the two numbers combined. (Square root of 8 times the square root of 5 equals the square root of 40.) So... √(-20) =√20×√(-1) =√4×√5×i =2i(√5) The answer is 2i times the square root of 5. square root (-20) = square root (-1) x square root (20) square root (-20) = i x 4.47213595 square root (-20) = 4.47213595 i
The square root of 75 is 8.66 and the square root of 20 is 4.47.
square root of 20 = square root of 4 * square root of 5. square root of 4 = 2, so your answer is 2 square root of 5.

20 is 5x4 so we can simplify it like this: ____ ______ / = / \/ 20 \/ 5 x 4 Also note that: ____ / = 2 \/ 4 So... ____ ____ / = / \/ 20 2 \/ 5
