How do you find the principal square root of a monomial?
Say the monomial is 4a squared. To find the square root to must do each part seperately. So square root of 4 is 2 and the square root of a-squared is |a| because we do not know the sign of a. The answer is 2|a|. If there is anything that cannot be "square rooted" then it would stay under a square root sign and just multiply by 2a as well. The principal root of a number is only its positive root (you can understand that you are looking for the principal root from the sign in front of the radical, which is a positive one)
A square root shows a number under?
the radical sign
What two numbers in square root 62 in between?
8 squared is 64 so it must be just under 8 and over, let me think... yes! 7!!
How do you find the square roots?
There is normally a square root button on your calculator The square root of a number is a number times itself. Most square roots are memorized, such as the square root of 16 being four. The easiest way to find a square root is using the root function on a calculator. you find the square route by thinking what times this number equals this number. For example.... the square route of 64 is 8 because 8x8 equals 64. Basically the same number times itself. Another example 12x12=144 notice the factors are the same.
How do you undo squaring a number?
To square a number, you multiply it times itself, for example 3^2 = 3x3 = 9. To "undo" the squaring of a number, you determine its square root. In this case, the square root of 9, or √9. If the number is a perfect square, then the answer is the number that you have to square to get the number under the radical, √. For instance, √9 = 3 because 3^2 = 3x3 = 9. For numbers that are not perfect squares, or for any other number that you find difficult to work with, use your calculator. Different calculators have different keys and instructions, so you should read the instructions that came with your calculator, or look up the instructions online.
What is thet square root of 9?
Simply put :3 If you want to know more The square root of a number is the positive number that squared will give the number under the square root
What is the method of working out the square root 120?
One way is trial and error. The square root of 121 is 11. So the square root of 120 is just under that. 10.9 squared is 118.81 10.95 squared is 119.9. 10.954 squared is 119.99 which is close enough for me.
What is the little 3 in maths called?
It can be an exponent (if you find it after your number) or a root (if you find it in the bend of the square root sign. In the square root sign that goes over a number, if there is nothing in the bend (or the "V") of the sign, then the sign indicates the square root of the number under the "roof" of the sign. If there IS a number in the "V", for instance 3, it means the cube root of the number under the roof; a 4 in the V means the fourth root, and so on. Think of a number under the roof of the square root sign as yielding the opposite value from the same number with an exponent of 2. If you put a number with an exponent of 2 under a square root sign, the result will be your original number: in other words, the square root of 2 squared is 2. If you want to express a square root without the square root sign, you could simply give your number an exponent of the RECIPROCAL of two (e.g. 9-1/2), which equals 3. In words, this means nine to the one-half power equals the square root of nine, equals 3.x2 -- the 2 is called a subscript which here means the second value of x, usually after being changed by a function, or perhaps it indicates the second value of x that will be used in your calculationx2 -- the 2 is called a superscript (or "power") which here means x to the second power (x squared).

What number under 50 is a square and triangular number?
1, the first triangular number, is also a square.
What is the largest square number under 200?
It is 196
Could a negative number be under a square root symbol?
Actually a negative number can be under a square root symbol. This becomes very useful in electrical calculations. The square root of -1 is j. That is, j2 = -1.
What is the number under the square root sign called?
radicand
What do you call the number under the square root symbol?
The radicand.
A square root shows a number under?
the radical sign
What happens when ninth root of a number is raised to the ninth power?
The power and the root cancel each other out and the result is the radicand (the number under the radical sign).
How do you find the square root of 89?
Find the factors of 89. Then put cancel out all of the factors that are perfect squares and put them outside of the root. Multiply the remaining factors under the root.
