When asked to write the prime factorization of the number 27 a student wrote 9 . 3. Explain the error and write the correct answ

kondor19780726 [428]

The correct prime factorization of 27 is 3 x 3 x 3

<em><u>Solution:</u></em>

Given that,

When asked to write the prime factorization of the number 27 a student wrote 9 . 3

So the student has written,

prime factorization of 27 = 9 . 3

This is wrong

Let us first understand about prime factorization

Prime factorization of a number is any of the prime numbers that can be multiplied to give the original number

A prime number is a whole number greater than 1 whose only factors are 1 and itself.

The first few prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23 and 29

Clearly from above list we can see that 9 is not a prime number

So the correct prime factorization of 27 is:

prime factorization of 27 = 3 x 3 x 3

Here "3" is a prime number

Find the distance between the two points in simplest radical form.

emmainna [20.7K]

The distance between the two points is $2\sqrt{5}$

Explanation:

Given that the two points are $(-8,-2)$ and $(-6,2)$

We need to determine the distance between the two points in simplest radical form.

The distance between the two points can be determined using the distance formula,

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Let us substitute the coordinates $(-8,-2)$ and $(-6,2)$ in the above formula, we get,

$d=\sqrt{(-6+8)^2+(2+2)^2}$

Simplifying the terms, we get,

$d=\sqrt{(2)^2+(4)^2}$

Squaring the terms, we get,

$d=\sqrt{4+16}$

Adding, we get,

$d=\sqrt{20}$

Simplifying, we have,

$d=2\sqrt{5}$

Thus, the distance between the two points in simplest radical form is $2\sqrt{5}$
