Answer:

4.2 x 10^9

1 x 10^9

7.4 x 10^8

6 X 10^8

3.7 X 10^7

Step-by-step explanation:

The higher the exponent the bigger it is, so arrange by powers first

1 x 10^9

4.2 x 10^9

7.4 x 10^8

6 X 10^8

3.7 X 10^7

Now put the numbers in order from biggest to smallest within exponent powers

4.2 is greater than 1   and 7.4 is greater than 6

4.2 x 10^9

1 x 10^9

7.4 x 10^8

6 X 10^8

3.7 X 10^7
