Question

When asked to write the prime factorization of the number 27,a student wrote 9•3.explain the error and write the correct answer

Answer 1

9 and 3 doesn't work because 9 can be simplified even more. It can be simplified down to 3 and 3.

So the true prime factorization of 27 would be 3*3*3 or 3^3

Hope this helps:)
