The number 100 can be expressed as a product of its prime factors using the following steps:
- Break down 100:
\( 100 = 10 \times 10 \)
\( 10 = 2 \times 5 \)
Therefore:
\( 100 = (2 \times 5) \times (2 \times 5) = 2^2 \times 5^2 \)
So, the correct expression of 100 as a product of its prime factors is:
\( 2^2 \times 5^2 \).
The corresponding option is:
2 squared times 5 squared.
