Following from greatest to least 5 * 10 ^ 3 3.2 * 10 ^ 8 1.2 * 10 ^ 8 7 * 10 ^ 5

Zina [86]

Answer:

3.2*10^8>1.2*10^8>7*10^5>5*10^3

Step-by-step explanation:

5*10^3 = 5000

3.2*10^8=320000000

1.2*10^8=120000000

7*10^5=700000

320000000>120000000>700000>5000

therefor

3.2*10^8>1.2*10^8>7*10^5>5*10^3
