Question

How many meters are in 7.50 ly?

I know exactly how to set it up but I have no clue what to do after I get 9.46*10^15(750)/1

Answer 1

7.50 light year has 7.09 ×
`10^(16)` meter.

Step-by-step explanation:

1 light year = 3 ×
`10^(8)` × 365 days

1 light year = 3 ×
`10^(8)` × 365 × 24 hours

1 light year = 3 ×
`10^(8)` × 365 ×24 × 60 minutes

1 light year = 3 ×
`10^(8)` × 365 ×24 × 60 × 60 second

1 light year = 9.46 ×
`10^(15)` m

Thus, 7.50 light year is given by,

7.50 light year = 7.50 × 9.46 ×
`10^(15)`

7.50 light year = 7.09 ×
`10^(16)` m

Hence, 7.50 light year has 7.09 ×
`10^(16)` meter.
