Is a square root of a negative number a real number?
no, it is an imaginary number represented by an i. For example, the square root of -4 is 2i.
Is the square root of any real number always positive?
The square root of a real number is not always positive. The square root of any positive number is positive, the square root of zero is zero (not positive), and the square root of a negative number is complex (i.e. neither positive nor negative). The square root of 16 = -4 or 4. The square root of 0 = 0 The square root of -16 = -4i or 4i
Is the square root of -4 irrational?
The square root of -4 is not irrational, it is imaginary. Irrational numbers are numbers that cannot be expressed as a fraction, like the square root of 2. Irrational numbers, however, are a subset of real numbers. The square root of -4 however, is not even a real number because no real number, when squared, gives -4. Therefore the square root of -4 is an imaginary number.In calculus, the root is expressed as 2i where iis the square root of -1.
Is the square root of negative 4 irrational or not real number?
It's irrational/not a real number
What is an imaginary number?
The square root of a negative real number is an imaginary number.We know square root is defined only for positive numbers.For example,1) Find the square root of (-1)It is imaginary. We say that square root of (-1) is i.In fact they are not real numbers.2) Find the square root of (-4)-4 can be written as (-1)(4)Square root of 4 is 2 and square root of (-1) is iSo, the square root of -4 is 2i.Similarly, we can find the square root of other negative numbers also.Source: www.icoachmath.comAn imaginary number is defined to handle square roots of negative numbers. The imaginary unit i is defined as the 'positive' square root of -1.
Is non-real numbers exist?
no, every number is a real number --- There are numbers that are not real numbers. They are called imaginary numbers, and have the property that when they are squared, the result is negative. The square root of -1 is called i, and the square root of any other negative number is i times the square root of the absolute value of the number. So the square root of -4 is 2i.
Why kind of a number is the square root of -4?
The square root of -4 is an imaginary number. Specifically, it can be expressed as 2i, where "i" is the imaginary unit defined as the square root of -1. Imaginary numbers are used in mathematics to extend the concept of numbers beyond the real number line.
Is the square root of negative four positive and negative?
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
How do you get square root of 16?
A square root of a number is a lesser number that when multiplied by it's self equals the larger number. The square root of 16 is 4. 4*4=16
Is the square root of 8 the number 4?
No. The square root of 16 is 4.
What is the difference between finding the square root of a number or finding the square of a number?
The square of number is a *a ( a number times itself ). For example, 4*4=16, so the square of 4 is 16. the square root is the number before you square it. The square root of 16 is 4. It actually simple to remember this way: think of the root as the root of a tree, growing to multiply itself.
Is the square root of 10 a real number?
Yes, the square root of 10 is a real number. It is an irrational number, meaning it cannot be expressed as a simple fraction, and its decimal representation is non-repeating and non-terminating. The square root of 10 is approximately 3.162, which lies between the integers 3 and 4 on the number line.
