1 fermometer / 10 light yeears =1.056970e-32

First of all,

What is "fermometer" ??

Make sure that you speel it correctly.

Second, I only can help you to calculate the answer of 10 light years.

---------------------------------------------------------------------------------------------------------------------------------------------------------

1 light year = 3 x 10⁸ x 60 x 60 x 24 x 365

                  = 9.4608 x 10¹⁵

∴ 10 light years = Ans x 10

                         = 9.4608 x 10¹⁶
