(i) 53 x 10^ -10 cm (10 to the power of -10)
(ii) 53 x 10^ -12 m
(iii) 53 x 10^ -3 nm
(iv) 53 x 10^ -6 micron
I think they're wrong.If they're correct please explain why.
Thanks a lot

0.53 is the same as 53 x 10^-2. All the answers follow from that.
An Angstrom is 10^-10 m.
i) A meter is 10^2 cm
0.53 x 10^-10 m = 53 x 10^-2 x 10^-10 m = 53 x 10^-2 x 10^-10 x 10^2 cm
ii) 53 x 10^-2 x 10^-10 m
iii) A meter is 10^9 nm 53 x 10^-2 x 10^-10 x 10^9 nm
iii) A meter is 10^6 micron.
53 x 10^-2 x 10^-10 x 10^6 micron
An Angstrom is 10^-10 m.
i) A meter is 10^2 cm
0.53 x 10^-10 m = 53 x 10^-2 x 10^-10 m = 53 x 10^-2 x 10^-10 x 10^2 cm
ii) 53 x 10^-2 x 10^-10 m
iii) A meter is 10^9 nm 53 x 10^-2 x 10^-10 x 10^9 nm
iii) A meter is 10^6 micron.
53 x 10^-2 x 10^-10 x 10^6 micron
