Answer: a) 3 × 10^4

b) 8 × 10^5

c) 9 × 10^6

Step-by-step explanation: a) 30000 = 3 × 10000

10000 = 10 × 10 × 10 × 10 = 10^4

so , 30000 = 3 × 10^4

b) 800000 = 8 × 100000 .

100000 = 10 × 10 × 10 × 10 × 10 = 10^5

so , 800000 = 8 × 10^5

c) 9000000 = 9 × 1000000

1000000 = 10 × 10 × 10 × 10 × 10 × 10

so , 9000000 = 9 × 10^6
