How to differentiate cube root?

Please guys! We are going to try a new formation today. There are six defenders, six defensive mbiss, six offensive mbiss, and one forward.

SUSO.

How? Three, three, three? There are lots of threes.

There is a PIPE.

Suso, if you don't pay attention, you'll go back to getting involved.

The coach is there.

You said it! The new scheme in attack is not because we are playing cube roots.

SUSO.

Is there a cube roots?

A coach.

Don't you know how to calculate a cube root? Do you know what it's about?

A person named Sara.

The first number is the cube root of a number, and it's the other number that's multiplied 3 times by itself.

The coach.

Who knows what the cube root of 27 is.

SUSO.

The cube root is 3. 27 is the number of 3 x 3 x 3.

The coach:

Yes...

3 times 3 gives us 9. 9 times 3 give us 27. Suso, you have barely saved yourself from being on the bench.

This time it is done in reverse.

The team captain's bib number is 10. If the root's result was 10. What would we be talking about?

There is a PIPE

You would have to add up the numbers 10, 10, and 10.

A coach.

1,000 is 10 x 10 x 10 If 10 is the cube root, that's right... The radicand is 1,000. The cube root is 10.

The coach is there.

Do you remember when calculating square roots?

PIPE:

Yes! The first number is given by the square root of a number.

The coach:

It was exact. The root's index was 2, since we added the number by ourselves.

The cube root has an index of 3, which is the number of times the number is added.

A person named Sara.

Those are very small numbers. How about calculating the cube root of a number?

The coach is there.

I am going to teach you a very simple method to calculate a cube root.

We scored 1,728 goals last year, which was the most by any team in the championship. What is the root of that number?

A woman named Sara.

Factor is the first thing we have to do.

It is the first step in figuring out a root.

The coach is there.

Sara, do you want to show us what the blackboard would look like?

To factorize, we need to divide the number into smaller numbers and then add them up.

Prime numbers can only be divided by themselves or by 1

We will start the factorization by trying the smallest prime numbers.

Until we find a division that is exact.

A woman named Sara.

A voucher! We put the figure on one side and the vertical line on the other, and then we divide the number between them.

I'm going to start by testing with the first prime number. 2. We can divide it evenly by 2 since 1,728 is an even number.

Half of 1728 was 864.

This number has an exact half.

Half of 432 is not.

Its half is 106.

And that is 27.

We can divide it by 3, which would be 9.

9 divided by 3 is 3.

3 divided by 3 is equal to 1

The one we would have finished is the end.

The coach:

Sara, it was very good. We can get a list of numbers on the right, if we add them all together.

2 x 2 x 2 x 2 x 2 x 3 x 3

The coach:

We can group the twos and threes into groups of three figures with this. Two groups with 2 x 2 x 2 and one group with 3 x 3 x 3. The cube root of 1728 would be the same as the cube root of 2 and 3.

The coach:

Remember?

Since the cube root's index is 3, we can only extract the numbers that are raised to 3. We can extract them all since they are raised to 3.

The result of the cube root of 1,728 is 2 x 2 x 3, and this gives us 12.

The coach is there.

We are going to verify that 12 is the cube root of 1,728.

How much does it cost us to raise 12 to the cube?

A person named Sara.

The result is 1,728. The operation is correct.

The coach:

Sarah was perfect! Thanks for your explanation.

To factorize, we have to divide the number that we have been given by the smallest prime numbers, and that's it!

Don't worry, there is a trick for each prime number.

It must be even for a number to be divided by 2.

If we get a multiple of 3, then it is divisible by 3.

For example. The multiple of 3 is the reason that 171 is a single digit number.

If it ends in 5 or 0, we can divide it.

Do you understand?

Everybody:
