Question 7 is= 2^2 * 3^3 * 5

Question 8 is= 5^3 * 4

Question 9 is= 16= 2*2*2*2

Step-by-step explanation:

7.

540 = 2*2*3*3*3*5

/ \ = 2^2 * 3*3 * 5

54 10

/ \ / \

6 9 2 5

/ \ /\

3 2 3 3

8.

500 = 5*5*5*4

/ \ = 5^3 * 4

5 100

/ \

20 5

/ \

5 4

9.

16 = 2*2*2*2

/ \ = 2^4

4 4

/\ /\

2 2 2 2

7. 540 = 18 × 30 = 2 × 2 × 3 × 3 × 3 × 5

8. 500 = 2 × 2 × 5 × 5 × 5

9. 3 × 3 × 3 × 3 = 81

Step-by-step explanation:

Prime Factorization: It is the multiplications of the prime numbers (It is the number which is greater than 1 and is a factor of itself or 1) to make the original number.

7. 540 = 18 × 30 = 2 × 2 × 3 × 3 × 3 × 5

8. 500 = 2 × 2 × 5 × 5 × 5

9. It is given that factors must be even and identical.

So it can be as 3 × 3 × 3 × 3 = 81
