Method 1: You experiment with different numbers. For example, to get the square root of 2: 1 squared = 1, and 2 squared = 4, therefore the root of 2 must be somewhere between 1 and 2. If you continue experimenting, you'll eventually find that 1.42 = 1.96, while 1.52 = 2.25, so the square root is somewhere between 1.4 and 1.5. Continue experimenting to find more and more digits.
Method 2 (much faster): Start with a preliminary estimate for the root, for example, estimate the square root of 2 as 1. Divide by the preliminary root, 2 / 1, the result is 2. That means that 2 x 1 = 2, the real root must be somewhere between both. Take the average, 1.5, as the next estimate for the square root.
Continue by dividing 2 / 1.5 = 1.3333. Take the average of 1.5 and 1.3333, which is 1.416.
Continue by dividing 2 / 1.416, etc.
The number of correct digits in the result tends to double with each step, making it much faster than the first method.

Square root of 900?
30. Square root is a number, times itself. 30x30 =900. Other examples of square root are 4x4=16, so 4 is the square root of 16. 5x5=25, so 5 is the square root of 25. 10 is the square root of 100, because 10x10=100.

What are the examples of irrational numbers?
The square root of any number which is not a perfect square;The cube root of any number which is not a perfect cube;Pi, the circular constant.e, the natural logarithm base number.
Square root 2 times square root 3 times square root 8?
square root 2 times square root 3 times square root 8
What is the square root 15 Times Square root 5?
The square root of 15 times the square root of 5 can be simplified as the square root of (15 * 5), which equals the square root of 75. The square root of 75 can be further simplified as 5 times the square root of 3. Therefore, the square root of 15 times the square root of 5 is equivalent to 5 times the square root of 3.
What are examples of radical?
Square root of 2, cube root of 5 are two examples.
How do you know whether a number is a perfect square?
A number is a perfect square when you can directly extract its square root in whole numbers and without approximation. When you subject a certain number to a radical sign, you can extract its square. Example: 25 is a perfect square. it's square root is 5, since 5 x 5 is equal to 25
How do you compute square root of 2 manually?
See the related link for a detailed description of a manual method for calculating square roots.
How can a make a batch file to know if a number is not a perfect square?
a number is a perfect square when you can directly extract its square root in whole numbers and without approximation. when you subject a certain number to a radical sign, you can extract its square. example: 25 is a perfect square. it's square root is 5, since 5 x 5 is equal to 25
Can you multiply two irrational numbers to get a whole number?
yes. Examples: the square root of 7 times the square root of 7 = 7 the square root of 7 times one over the square root of 7 = 1
What are examples of square roots?
4 is the square root of 16 because 4x4=16. 5 is the square root of 25 because 5x5=25
Square root of 900?

Is the square root of three irrational or rational?
The square roots of three are examples of irrational numbers.
How do you rationale the denominator?
Depends on the situation. You usually have to multiply numerator and denominator by some number or expression. Examples: 1 / square root of 2 Here, you have to multiply numerator and denominator by the square root of 2. 1 / (square root of 2 + square root of 3) Here, you have to multiply numerator and denominator by (square root of 2 - square root of 3).
Step on how to extract square root?
No luck here.... Sorry...no one has answered this question no answer sorry keep searching
What are two examples of irrational numbers?
pi and the square root of 2
Is the square root of a decimal always an irrational number?
Not necessarily. The square root of 2.56 equals 1.6, and the square root of 0.25 equals 0.5, for two examples. If the decimal represents a rational number that is a fraction of two perfect squares, then the square root will be a rational number. The two examples I gave were 2.56 = 256/100, and 0.25 = 1/4.
