still 1

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.)

### How can you solve the equation x2 plus 3i equals 0?

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!

### 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

### Square root 14 divide into square root 7?

square root of 14 divided by the square root of 7 is the same as
the square root of 14/7, so the answer is square root 2
((14)^(1/2))/((7)^(1/2))=(14/7)^(1/2)=2^(1/2)
Clarification: The question means: square root of 7 divided by
square root of 14
So that's about 0.7071067 (square root of a half, not square
root of 2).

### What is the square root of -28?

the square root of -28 is the square root of -1 time the square
root of 28. The square root of -1 is not a real number, it is
represented by i. The square root of 28 is the square root
of 4 times the square root of 7 (4*7=28) The square root 4 is equal
to 2, and the square root of 7 cannot be simplified.
The answer is 2i√7.
