what is the simple method of square root
Answers
Step-by-step explanation:
whole numbers that are the product of other whole numbers. For instance, 25, 36, and 49 are perfect squares because they are 52, 62, and 72, respectively. Perfect square factors are, as you may have guessed, factors that are also perfect squares. To start finding a square root via prime factorization, first, try to reduce your number into its perfect square factors.[2]
Let's use an example. We want to find the square root of 400 by hand. To begin, we would divide the number into perfect square factors. Since 400 is a multiple of 100, we know that it's evenly divisible by 25 - a perfect square. Quick mental division lets us know that 25 goes into 400 16 times. 16, coincidentally, is also a perfect square. Thus, the perfect square factors of 400 are 25 and 16 because 25 × 16 = 400.
We would write this as: Sqrt(400) = Sqrt(25 × 16)

Take the square roots of your perfect square factors. The product property of square roots states that for any given numbers a and b, Sqrt(a × b) = Sqrt(a) × Sqrt(b). Because of this property, we can now take the square roots of our perfect square factors and multiply them together to get our answer.[3]
In our example, we would take the square roots of 25 and 16. See below:
Sqrt(25 × 16)
Sqrt(25) × Sqrt(16)
5 × 4 = 20
Answer:
square roots are very easy you just have to multiply the number by its self for example:-
