Answer 24

you don't
you keep it like that
like how they kept their numbers like 3.54 * 10^7

@jigglypuff314

Answer 29

if you wanted to
you can keep your answer like that
he just wanted you to make sure the 1.18 and the 10^-1
were together
because in your first post you were saying that just 10^-1 was the answer
