Question

Please help.

Answer 1

All you have to do is move the decimal place to the right 4 times (if the 4 was negative, the decimal would be moved to the left):

1.56 x 10^4 = 15,600

So 1.56 x 10^4 in standard notation is 15,600 s.

Answer 2

Ok. How would I make that in hours?

Answer 3

If s=seconds, then there are 60 seconds in one hour. All you have to do is divide the number you got by 60:

15,600/60 = 260 hours.

The answer would be 260 hours.

Answer 4

Wouldn't that be 260 minutes, not hours.

Answer 5

Oh, right, sorry. Then just divide it by 60 again:

260/60 = 4.33 hours or \[\frac{ 13 }{ 3 }\] hours
I don't know if your teacher wants it in decimal or fraction form.
