Treat it like a positive and add an i. Explanation: The square root of negative nine is equal to the square root of nine times negative one is equal to the square root of nine times the square root of negative one. The square root of negative one represented by an italic lower case i. The square root of negative nine is 3i. √-9 = √9 * -1 = √9 * √-1 = 3i

9 square root 4 minus 12 square root 4 = -6

no, it is actually not a real number. It falls under the category of a imaginary number which is the square root of -1 or as the variable i Because the square root of -4 is 2i because the square root of 4 is 2 and if you take i out it will maek it a positive so it goes like this -4 SR= 2i -9 square root= 3i and so on

-9

9

-3

Square root of 9: 3Square root of -81: 9i The product of both is 27i

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.

The square root of 81 is 9 and the square root of 4 is 2!

3i and or -3i

They all have square roots. Square root of 1 is 1 Square root of 4 is 2 Square root of 9 is 3

sqrt(4) = 2 sqrt(9) = 3 Therefore, the square root of 4 plus the square root of 9 is equal to 2 + 3 = 5.

There is no square root for a negative number. It is an imaginary number.

Since the numbers are complex, let's re-write the question as:i*sqrt(4) * i*sqrt(9)i^2, by the good graces of algebra, is equal to -1, so your answer simplifies to:= -1 * sqrt(4) * sqrt(9)= -1 * 2 * 3= -6

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.

Yes. -9 (that is, negative 9)

81 because there are no negative square roots

3i the letter "i" is a complex number in mathematics. it stands for the square root of negative one. since you cannot take the square root of negative numbers in your caculators the correct way to represent it is by putting an "i" in the place of the square root of negative one.

Square roots can be positive or negative. 9 x 9 = 81 -9 x -9 = 81 9 is the positive square root of 81.

Square root 2 is the square root of 4 3 is the square root of 9 and so on

What do you get when you multiply positive 3 by itself ? (You get 9.) What do you get when you multiply negative 3 by itself ? (You get 9 again.) The square root of a number is something which, when you multiply it by itself, gives you the number. When we multiplied positive 3 by itself, we got 9. So positive 3 is a square root of 9. When we multiplied negative 3 by itself, we got 9 again. So negative 3 is also a square root of 9. Every positive number has two square roots. They're both the same digits, but one is positive and the other one is negative.

The square root of the fraction 4/9 is either 2/3 or -2/3

No - a square root of a negative number is an imaginary number. for example, sqrt(-9) is equal to 3i.
