The value of cube root of one is 144.
The nearest previous perfect cube is 125 and the nearest next perfect cube is 216 ..
Does a square root have 2 answers?
It has multiple answers so why do we pick the positive one? if x2=16⟹x=√16 or x=−√16 for respectively the positive and negative solution. This implies that the square root function has a single answer and we must negate its answer to obtain the second solution.
Is negative square root of 16 a real number?
There is no Real number whose square is −16 .

Is a square root of 25?
The principal square root of 25 is √25=5 . Example 2: Find the real roots of the equation x2=100 .
Is the square root of 4 plus or minus 2?
Although the principal square root of a positive number is only one of its two square roots, the designation “the square root” is often used to refer to the principal or nonnegative square root √ b. This is why √4 = 2, rather than ‒2.
Are all square roots positive?
Yes, it will always be the positive number. The point is that, by convention, square root refers to the principal square root. You say that square root only refers to the positive, yet for the first one you say it has 2 solutions.
What do you call plus and minus signs?
U+2010 ‐ HYPHEN. (many) – Dash. The plus and minus signs, + and −, are mathematical symbols used to represent the notions of positive and negative as well as the operations of addition and subtraction. Their use has been extended to many other meanings, more or less analogous.
What is the square of a negative number?
Yes, you can square a negative number. In fact, any number at all can be squared, even numbers like pi and 0. This is because to square a number just means to multiply it by itself. For example, (-2) squared is (-2)(-2) = 4.
What is the square root of a negative 4?
TL;DR: It’s undefined, or doesn’t exist/is an imaginary number, because you can’t take the square root of a negative number. A square is the result of a number, multiplied by itself; when the two are whole numbers, the result is a perfect square. For example, 16 is a square – 4*4 = 16 – and so is 25 – 5*5 = 25.
What are the real square roots of 144?
The value of the square root of 144 is equal to 12. In radical form, it is denoted as √144 = 12.
What are the 2 square roots of 144?
So the set of all real square roots of -144 is the empty set. The imaginary square roots are i12 and -i12.
Why is the square root always positive?
The reason for this distinction is that in a mathematical function f(x, y) for every value of x, there has to be a unique value of y. Thus, the square root of 4 cannot be +2, -2, by definition! Thus, as a norm, we only take the square root function to be positive.
WHY IS 144 a perfect square?
A number is a perfect square (or asquare number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, thesquare root of 144 is 12. Therefore, thesquare root of 144 is an integer, and as a consequence 144 is a perfect square.
What is 4 the square root of?

Why is i the square root of negative one?
Here, the term “imaginary” is used, because there is no real number having a negative square. There are two complex square roots of −1, namely +i and −i, just as there are two complex square roots of every real number other than zero (which has one double square root).

What are the positive and negative square roots of?
The term (or number) whose square root is being considered is known as the radicand. The radicand is the number or expression underneath the radical sign, in this example 9. Every positive number x has two square roots: √x, which is positive, and −√x, which is negative.
When a square root is negative?
To indicate that we want both the positive and the negative square root of a radicand we put the symbol ± (read as plus minus) in front of the root. Zero has one square root which is 0. Negative numbers don’t have real square roots since a square is either positive or 0.
