    Answer:

    4^3×5^2, 7^2×9^4

    Step-by-step explanation:

    Where a^b means a to the power b. When writing on paper b should be small and above and to the right of a. Keep the bottom numbers in order, so 4 before 5 and so on. In a there are 3 4s and 2 5s, hence the answer. Same reasoning for b.
