Question

Using dimensional analysis, convert 3.6 years into seconds. (1 year=365 days, 1 day=24 hours, 1 hour=60 min, 1 min=60 seconds)

1.1 x 10^ -7 seconds
8.3 seconds
1.9 x 10^6 seconds
1.1 x10^8 seconds

Answer 1

I know the answer is 113,605,027.2 seconds, but I don't know how to put it in the right form...

Answer 2

By shifting decimal point of 113,605,027.2, 8 places to left you get the answer 1.13 x 10^(8). for example, you can write 234.4 as (234/100) x 100 = 2.34 x 10^(2).
