Many ways to determine the square root of a number. you can use Square root calculator as Algebra solver .Of the many ways in this, we need to choose the most appropriate and suitable for us or our children.

Let's try to learn a variety of ways to calculate square root to solve Linear equations problems.

1. Trial and error. This is the most common way to solve the square root calculation. This method is suitable for children, we, who have been smoothly calculates the square or multiplication.

For example we will calculate the roots of (squared) of 64.

So we try to 5 × 5 = 25 (too small).

Try 9 × 9 = 81 (too big).

Try the 7 × 7 = 49 (too small).

Try the 8 × 8 = 64 (right).

So we get the root of 64 is 8.

2. How factorization. This is quite interesting and tactical. For example, berpakah root of 64?

So 64 = 2 × 32 = 2x2x16 = 4 × 16

Then

root 64 = 4 x root root 16

= 2 x 4

= 8 (Done).

This factorization is very useful way to high-level math. When sitting in high school, we often use the way of factorization. When college calculus, we also often use factorization.

For example, what is the root of 72?

Then

72 = 9 × 8 = 9x4x2

So root root 72 = 3x2x 2

= 6akar2 = 6 √ 2.

3. How to approach. This method is a variation and continuation of the trial and error. After practicing a few times, we will be very proficient in this way. This approach is very powerful way to calculate the root whose value is quite large.

For example, what is the root of 1681?

Most sensible approach is 40 × 40 = 1600.

Because 1681 is 1 unit of the unit from the roots of 1 or 9. In this case we memilh 1. (Why?).

So we get the answer 40 1 = 41

For example, what is the root of 3364?

Most sensible approach is 50 × 50 = 2500.

(While 60 × 60 = 3600, too big).

Because the unit of 3364 is 4 then the unit from its root is 2 or 8. In this case we choose 8. (Why?)

So we get the answer 50 8 = 58.

4. And others. Of course there are many ways we can do to calculate square roots. Keep creating. Discover how the most appropriate for your child.

As a Math problem solver, interesting material, including material that is the square root is preferred. Interesting root looks like hard. But quite understand how it is very easy. What else when learning while playing. Algebra 1 also developed a way to draw the square root 3 (cubic root) is fun for College algebra problems.

How do you think?try to find Math answers there!
