Question

Which of the following shows a number as a product of prime numbers in exponential form? Choose all that apply.

Answer 1

The first expression 3^2 · 5 · 7 and the fourth expression 3^3 · 11 show a number as a product of prime numbers in exponential form.

3^2 · 5 · 7 shows 315 as a product of prime numbers 3, 5 and 7, that is 3 · 3 · 5 · 7 

In 4^2 · 5 · 7, the number 4 is composite which can still be written as product 2 · 2

For the third one 3^3 · 8, the number 8 is composite which can still be written as product 2 · 2 · 2

The fourth expression 3^3 · 11 shows 99 as a product of prime numbers 3 and 11 which is 3 · 3 · 11
