The number 100 can be expressed as a product of its prime factors.
To factor 100:
- First, we can note that \(100 = 10 \times 10\).
- Next, we can factor 10 further: \(10 = 2 \times 5\).
So: \[ 100 = 10 \times 10 = (2 \times 5) \times (2 \times 5) = 2^2 \times 5^2 \]
Thus, the correct expression of 100 as a product of its prime factors is:
\(2^2 \times 5^2\).
