When a negative value does not make sense.
Suppose you are told that a square has an area of 9 square metres and asked to find the lengths of its sides.
Side = sqrt(Area)
So length of side = sqrt(9) = -3 metres or +3 metres. However, length cannot be negative and so you reject the negative square root.
However, if you were told that the same square was located on the Coordinate plane with one vertex at the origin and one side along the x-axis. Then one of the vertices could be at (3, 0) or (-3, 0). So the answer to the original question is that it depends on the context.

How do you calculate square root 2?
You can use logrithms.Take your log table.Look for the log value of 2.Now divide that value by 2(you should devide by 2 if you want square root,devide by 3 if you want cubic root).Now take the antilog value.It is equal to square root.
If you divide 4 by the square root of -7 and then times that by the square root of sin30 how many swag points will you gain?
I am not sure what you want to calculate; anyway, the square root of a negative number is a complex number: in this case, "i" multiplied by the square root of 7. The remaining calculations will also result in complex numbers. When you calculate points, you usually want a real number, not a complex number.
What is the square root negative 16 over 9?
sqrt(16/9) = sqrt(16) / sqrt(9) = 4/3 .That's the square root of positive 16/9. There is no square root of a negative number, unlessyou want to get into what's called "imaginary" numbers in math and engineering.If you want the square root of -(16/9), or (-16)/9, or 16/(-9), in each case it's (4/3)i .That little ' i ' is the unit imaginary number, defined as the square root of (-1).That's probably as far into it as we ought to go for right now.
Why is the square root of any real number is always sometimes or never positive?
Sometimes.The square root of a positive number is positive.The square root of zero is zero.The square root of a negative number is a complex number - if you want only real numbers, you can say that it is undefined, and many calculators will give you an error message.
How do you find the square roots of fractions?
Square rootsTo find the square root of a number, you want to find some number that when multiplied by itself gives you the original number. In other words, to find the square root of 25, you want to find the number that when multiplied by itself gives you 25. The square root of 25, then, is 5. The symbol for the square root is . Following is a partial list of perfect (whole number) square roots.Note: If no sign (or a positive sign) is placed in front of the square root, the positive answer is required. No sign means that a positive is understood. Only if a negative sign is in front of the square root is the negative answer required.A fraction, or fractional number, is used to represent a part of a whole. Fractions consist of two numbers: a numerator (which is above the line) and a denominator(which is below the line).So to work out the square root of a fraction you find the square root of the numerator and put it above the square root of the denominator.
The square root of a negative value is called an imaginary or number?
Yes. The letter i denotes the value of the "positive square root" of -1. So i² = -1. But also (-i)² = -1 as well. Remember that for every number there is a "positive" and "negative" square root. So if you want the square root of -4, you can do this: -4 = (-1)(4). So sqrt(-4) = sqrt[(-1)(4)] = sqrt(-1)*sqrt(4) = i*2 or -i*2. We usually write these as 2i and -2i.

How do you find the nearest perfect square?
There is no formula relating to a perfect square but if you want a method 1. Find square root(x) 2. Take the integer component (integral value) of square root(x) 3 Add 1 to intenger(square root(x)) 4. square it So: (integer(square root(x)) + 1)^2
Square root of -1.375?
If you want a real number as an answer, then there is no solution - no real number squared will give you a negative result. If complex numbers are acceptable, just take the square root of the positive number, and add an "i" at the end. For example, the square root of (-4) is 2i. Whether or not a complex number is acceptable depends on the kind of problem. The same happens for negative and fractional numbers; for some problems, a negative number is acceptable as an answer, for others not.

What to use square root in Excel?
To do square root in excel you type SQRT and then whatever number you want to square root in brackets. For instance, if you want the square root of 13 in one cell, you would type =SQRT(13).
What is the square root of negative 4?
That greatly depends on what level of math you are taking. Early math classes might want you to say, "You can't take the square root of a negative number." Later math will talk about real numbers and still the answer would be, "The square root of -4 does not have a real answer." Still later in your math career you will see imaginary numbers whereby the special character "i" is equivalent the the square root of -1. If imaginary answers are allowed, then the square root of -4 = 2i (since -4 is the same as -1 x 4, the square root of -1 x 4 = i x 2 =2i)
Is there a square root for a negative number?
Yes there is Finding the suare root of negative numbers involves using imaginary number 'i'.The value of i is taken as (-1)^(1/2). That is, i=(-1)^(1/2). Now, suppose you want to find sq. root of -25. -25=25*(-1) Taking sq. root on both sides we get (-25)^(1/2)=25^(1/2)*i {since (-1)^(1/2)=i} Therefore root of -25 is 5i. Although, we have found root for -25 this method is general and can be applied for any negative number.
