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
