What is the square root of negative 81?
The square roots of -81 are ±9i where i is the imaginary square root of -1.
What is the square root of negative 27 divided by square root of 3?
9
What are the Order of Operations when simplifying a negative square root if using the quadratic formula to solve a quadratic formula?
The usual rules for "order of operation" apply. Don't forget that the square root of a negative number is an imaginary number. As an example, the square root of -9 is 3i (that is, the square root of +9, times the "imaginary unit").
Is the square root of 9 a rational number?
No - a square root of a negative number is an imaginary number. for example, sqrt(-9) is equal to 3i.
What is the number i?
i is the symbol for an imaginary number, a complex number with the property i2=-1. The square root of a negative number is the square root times i. For example, the square root of -9 = 3i.
Find the Square Root -81?
There is no square root for a negative number. It is an imaginary number.
What is the square root of negative 81?

Square root of -9 25?
The square root of -9/25 is 0.6i or -0.6i, where i is the imaginary square root of -1.
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.
What is an imaginary number and how is it expressed?
An imaginary number is a number that cannot exist. An example of an imaginary number would be: the square root of negative nine, or any negative number. When I try to think of any two of the same numbers that would multiply together to be negative nine, all I can think of is 3 or -3. when I square both of those numbers, I get the number 9, not -9. When I multiply two negatives together, I get a positive number, therefore there is no possible way to get the square root of -9, or any negative number.

What does I mean in square root -1?
The square of any real number is non-negative. For example (-3)2 = +9 So, no real number can have a negative square root. Occasionally, though, mathematicians come across the need to find the square root of a negative number (for example in solving some quadratic equations). So they invented a family of numbers called imaginary numbers and the i (lower case) stands for the imaginary square root of -1. Apart from having a negative square, they are just like "ordinary" real numbers.
What real number subsets are square root numbers in?
if there is no integer answer, they are irrationalex. sq root 5 is irrational but sq root 9 = 3 so it is rational,integer, counting numberif you are taking sq root of a negative they are imaginary ex. sqroot (-9)=========================The square roots of all positive real numbers are real numbers.The square roots of all negative real numbers are imaginary numbers.Some square roots are rational, but the vast majority are irrational.
