Simplify the quotient 4.5x10^5/9*10^7. Write your answer in scientific notation show work

Remember

(ab) / (cd) = (a/c) (b/d)

and

(x^m) / (x^n) = x^ (m-n)

and (x^m) (x^n) = x^ (m+n)

so

(4.5x10^5) / (8x10^7) =

(4.5/8) ((10^5) / (10^7)) =

(0.5625) (10^ (5-7)) =

(5.625x10^-1) (10^-2) =

(5.625) (10^-3)

it is 5.625 times 10⁻³
