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.
What is the difference between a positive and negative square root?
The positive square root of a number is the non-negative value that, when multiplied by itself, equals the original number, while the negative square root is the negative counterpart of that value. For example, the square roots of 9 are +3 and -3, where +3 is the positive square root and -3 is the negative square root. In mathematical notation, the positive square root is often denoted as √x, while the negative square root can be expressed as -√x.
How many square roots does a number 20 have?
A number like 20 has two square roots: one positive and one negative. Specifically, the square roots of 20 are √20 and -√20. In general, any positive real number has two square roots, while zero has one, and negative numbers have no real square roots.
What is the first square number and cubic number?
The first square number is 4 while the first cubic number is 8. Condition: you do not consider 1 as an answer since 1x is surely 1 for any value of x, from negative to infinite.
What does a negative number times a negative number equals?
negative multiply by negative is positive. While negative added with negative is negative. E.g. - 2 x -2 is 4 while -2 + -2 is -4

Do Positive numbers have negative square roots?
Every positive number has two square roots. Their absolute values are the same. One is positive and the other is negative.
What is a sqare whole number?
That is any number that is an integer, and the square of another integer. For example, 4 is the square of 2, while 9 is the square of 3.That is any number that is an integer, and the square of another integer. For example, 4 is the square of 2, while 9 is the square of 3.That is any number that is an integer, and the square of another integer. For example, 4 is the square of 2, while 9 is the square of 3.That is any number that is an integer, and the square of another integer. For example, 4 is the square of 2, while 9 is the square of 3.
Which is greater the square root of 3 or the square root of 7?
To determine which is greater between the square root of 3 and the square root of 7, we can compare their values. The square root of 3 is approximately 1.732, while the square root of 7 is approximately 2.646. Therefore, the square root of 7 is greater than the square root of 3.
How do you simplify the square root of -96?
In simple terms, negative numbers don't have square roots. If you multiply a number by itself, you can never get a negative number for the answer. Square a negative or a positive, you get a positive; square zero, you get zero.Now, if you get fancy, you could say that while a negative number has no real square roots, you can make one up by inventing the imaginary number i, which is the number that when squared, equals -1. Then you can say that sqrt (-96) = [ sqrt(-1) ] * [ (sqrt(96) ] = i*sqrt(96). From here, you can go ahead and simplify sqrt(96) ...Look for a perfect square factor, and take it out of the root: 96 = 4x24 = 4x4x6 = 16x6; sqrt(96) = sqrt(16)*sqrt(6) = 4sqrt(6).So sqrt(-96) = i*4sqrt(6), which is customarily written as 4isqrt6(You would write a radical sign wherever it says "sqrt" above.)
How is an english double negative like subtracting negative number?
subtraction is merely adding a negative number, so subtracting a negative number is adding the negative of a negative number. It should be pointed out that while most people find this concept obvious, it was not obvious to ancient mathematicians. In fact, as late as the 1800s, most mathematicians thought that negative numbers were nonsense.
