Do I have the correct solutions when expressing the above in a and b?

We have
[tex]1.2\text{ }\times10^{44}\text{ Joules}[/tex]We need to put this quantity in
a. Kilojoules
we have the next equivalence to convert J to KJ
1000 joules = 1 kilojoule
[tex]\frac{1.2\times10^{44}}{1\times10^3}=1.2\times10^{44-3}=1.2\times10^{41}KJ[/tex]b. nano joules
we have the next equivalence to convert J to nJ
1J = 1000000000 nJ= 1x10^9 nJ
[tex](1.2\times10^{44})(1\times10^9)=1.2\times10^{53}nJ[/tex]
