Engineers and scientists do work with square roots of negative numbers,
but when they do, the square root is called an "imaginary" number, and
they need a special symbol for it.
For our purposes, and the level of math typically encountered here on WikiAnswers,
the best answer is simply to point out that you can't find any number which, when you
multiply it by itself, gives you a negative answer, so there's no such thing as the
square root of a negative number.
48 in a square root sign
square root of a negative number is imaginary square root of negative 1 is defined as i square root of negative 144 is sqrt ((144)(-1)) = 12i
Oh, what a happy little question! When you have the square root of ten over the square root of forty, you can simplify it by dividing the square roots. So, the answer is the square root of ten over the square root of forty simplifies to one over the square root of four, which simplifies further to one over two. Just a little math magic to brighten your day!
The square root of a negative number is not real.
Nothing. You cannot have a square root of a negative number. The square root of negative one is called i, but i is an imaginary number. It does not exist and does not follow the properties of real numbers. (For example, if a and b are positive, then the square root of a times the square root of b is the square root of ab. But the square root of -7 is not the square root of 7 times i.)
48 in a square root sign
The square root of negative forty-nine (-49) has no value over real numbers. However, over complex numbers, the square root of -49 is ±7i, where "i" is the imaginary unit, which i2 = -1.
Remember when taking the square root of a number, that there is the positive answer, but also there is a negative numbert answer. An example is the square root of 49 can be either 7 or negative seven, because when you multiply negative seven times itself, you get forty nine.
