V kno that- x- is +. Now when u sqare a negative no it means occouring 2 times and cancel out each other.
For example-
-2 x -2=4
============================ (a second answer.)
Every real number is either negative, positive or zero.
When you square a number, you multiply it by itself, so if
you square a negative number, you are multiplying a negative by a negative which gives a positive. If you square a positive, you multiply a positive by a positive and get a positive. If you square 0 , get 0. Therefore, in no case is the answer negative.
( It is harder to explain why a negative times a negative is positive.)

Does negative 3 squared equal negative nine?
No. Negative three squared is POSITIVE nine. The square of ANY number is positive, because if you multiply a negative number by a negative number, the result is positive.
Why is square root of the number -9 not a real number?
Well, honey, the square root of a negative number like -9 isn't a real number because in the real number system, the square root of a negative number isn't defined. You gotta step into the world of complex numbers if you wanna play with those imaginary roots. So, in short, the square root of -9 is as real as a unicorn riding a rainbow.
Is the square root of -24 rational?
No. The square root of -24 isn't even real, let alone rational because the square root of any negative number is going to be an imaginary number.
What is an unreal number?
Imaginary and complex numbers are an extension of the Real Number system. They are not called unreal. An imaginary number is a non-existent number, like the square root of a negative number. For example, the square root of -4 is 2i (i stands for imaginary). There are also complex numbers, which are defined as the sum of a real number and an imaginary number (e.g. 4 + 3i). An imaginary number does not exist, but can nevertheless be useful in certain applications. An imaginary number is any number that is the product of a real number and the square root of negative one (-1). The square root of -1 is the "unit" of the set of imaginary numbers, and is referred to as "i". As you know, negative numbers cannot have square roots, and so the square root of any negative number is "imaginary". There are also "complex numbers", which are the sum of a real number and an imaginary number. For example 3 + 2i.
Can a perfect square have a negative square root?
If a is any number, then a squared = (-a) squared, so one might say that a and -a are both square roots of a squared. However, the square root symbol always means the positive square root.
What is the square root if negative 3?
It doesn't have a square root, it is impossible because any number times itself is a postive.
What is a number that is a square root of a negative number?
I think it is Xi (whatever the square root of the positive is times i). i is an imaginary number that when you square it, it becomes negative. eg. the square root of -4 is 2i. Without "i", it would be impossible to square root a negative number, as any number times itself will always equal a positive.
What the square root of negative five?
first of all the square root of any negative number is technically impossible, but in certain maths it can be accepted in terms of imaginary number, i. so to answer your question it is about 2.236067977i
When can the square of a negative number be negative?
This can never be. The square of any number will always be positive. Any positive number multiplied by another positive number will be positive, while any negative number multiplied by another negative number will be positive.
Is the square root a real number?
The square roots of any positive real number are a positive and a negative real number. The square roots of any negative real number are a positive and a negative imaginary number. The square roots of any imaginary number or any complex number are two complex numbers.
Is there a number that doesn't have a square root?
Any negative number, and infinity. However, a number (called "i") was created to represent the square roots of negative numbers.
What is square root of negative five squared?
first of all the square root of any negative number is technically impossible, but in certain maths it can be accepted in terms of imaginary number, i. so to answer your question it is about 2.236067977i
Why square root of negative 36 is not a real number?
When you multiply any number by itself, the result is always positive. You cannot take any real number and square it to get something negative. The square root of -36 is 6i.
Is the square root of negative 101 a rational number?
The square root of any negative number is not even a 'real' number. It's called 'imaginary', because there's no number you can multiply by itself to get a negative number. The square root of 101 is irrational.
Is the square root of any real number always a real number?
No, it is not, because real numbers include negative numbers. The square root of a negative number is an imaginary number
When squaring a negative number if the factor is a negative and the exponent is positive will your answer be negative or positive?
If you square any real number it will always be positive.
Why is any number raised to a even power positive?
A positive number times a positive number is always positive. A negative number times a negative number is always positive. Therefore, any square number will be positive. Any number to the fourth power (a square times a square) will always be positive. And so on.
