Best Answer

The square root of -1 is usually marked as undefined. however if you would like to go through or past Algebra 2 then the answer would be i, or imaginary. There is no definite answer in the realm of real numbers so the answer comes to be imaginary. So if you see a t-shirt, or flair button on facebook, that starts with the "square root of negative one" symbol followed by a heart - it symbolizes: "I Love...".
i, an imaginary number.

The square root of 1 is plus or minus 1. √1 = ± 1 The reason is that 12 = 1 and -12 = 1. (Either 1 squared or minus 1 squared equals one.)

The square root of 1 is also 1, so then you just take the square root of that, which is, again, 1.

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!

What is the square root of negative twenty?

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
