Answer:

This is not a prime factorization.

The correct prime factorization is
2^5*3*5^4*11^2

=======================================================

Further Explanation:

The expression your teacher gave you is not a prime factorization because the 8 isn't prime.

8 = 2*2*2 =
2^3

If we replace 8 with
2^3, then we go from


2^2*3*5^4*8*11^2

to


2^2*3*5^4*2^3*11^2

and that rearranges to


2^2*2^3*3*5^4*11^2

Then we can simplify the
2^2*2^3 portion to get
2^5 since we add the exponents while keeping the base '2' the same.

We therefore end up with


2^5*3*5^4*11^2

as the correct prime factorization. Each base (2,3,5,11) is a prime number.

---------------

As a check, use your calculator to type in

2^2*3*5^4*8*11^2

and also

2^5*3*5^4*11^2

and you should get the result of 7,260,000 each time. Since we get the same result, this confirms 2^2*3*5^4*8*11^2 = 2^5*3*5^4*11^2
