There is no square root of -75. If it's 75, that is 5 square root 3.
-21 and -20, or 20 and 21.
There is no true answer to the square root of twenty, Because you can't multiply two of the same numbers to make twenty.
20
42 is 16, less than 20 52 is 25, more than 20. so, 20 is not a perfect square, and does not have an integral square root. But, the square root of any integer is either an integer itself, or irrational. So, square root 20 is irrational
It is 2*sqrt(5).
The sqare root of 20.

There is no square root of -75. If it's 75, that is 5 square root 3.
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
20 is one of the two square roots of 400.
There are two answers: 20 and -20
Sqrt of 200+(6*20) = 134.1421356
You can always add radicals, but you can't simplify unless the radicands have a common factor. For example, the square root of 20 plus the square root of 45 equals 2 times the square root of 5 plus 3 times the square root of 5, which is 5 times the square root of 5.
The square root of 75 is 8.66 and the square root of 20 is 4.47.
√(w+20)=4 Square both sides: w+20=16 w= -4
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.
