To express 225 in index form, we can factor it as (15^2) since (15 \times 15 = 225). The number 25 can be expressed as (5^2) because (5 \times 5 = 25). Therefore, (225 \times 25) can be rewritten as ((15^2) \times (5^2)). Converting 15 into its prime factors gives us ( (3 \times 5)^2 = 3^2 \times 5^2), so the full expression becomes (3^2 \times 5^2 \times 5^2 = 3^2 \times 5^4).
