Could you explain this?
("Dumb it down for me")
So far I know that 2^2 x 3 x 5^4 x 8 x 11^2
is equal to 4 x 3 x 625 x 8 x 121. (I think)
==========================================
A number is written with the following factorization: 2^2 × 3 × 5^4 × 8 × 11^2. Is this factorization a prime factorization? Explain why or why not. If it is not correct, give the correct prime factorization of the number.
I don't need the answer I just need the question explained.
prime factorization:made up of primes, each to some power. In this case, 2,3,5,11 are primes, but 8 is not, it is 2^3, so prime factorization should be
2^5 * 3 *5^4 *11^2
Ah. Thank you.
do you know what the number the prime factorization is of?
To determine if the given factorization is a prime factorization, we need to check if all the factors are prime numbers, and if there are any missing prime factors.
Let's break down the given factorization:
2^2 × 3 × 5^4 × 8 × 11^2
First, let's address 8. It is not a prime number because it can be broken down into smaller factors: 2 × 2 × 2. So, we can rewrite the factorization as:
2^2 × 3 × 5^4 × 2 × 2 × 2 × 11^2
Next, let's focus on 5. The exponent of 5 is 4, which means we have four 5s multiplied together. To simplify this, we can write it as 5 × 5 × 5 × 5, which is the same as 5^4.
Now, let's sort the factors in ascending order:
2^2 × 2 × 2 × 3 × 5 × 5 × 5 × 5 × 11^2
We can see that both 2 and 5 are repeated factors. We can combine those repeated factors by multiplying them together:
2^2 × 2 × 2 × 3 × 5^4 × 11^2
Now, let's simplify the repeated factors:
2^3 × 3 × 5^4 × 11^2
This is the correct prime factorization of the number.
So, to summarize:
The given factorization, 2^2 × 3 × 5^4 × 8 × 11^2, is not a prime factorization because it includes the factor 8, which is not prime. The correct prime factorization of the number is 2^3 × 3 × 5^4 × 11^2.
