Answer 1

What is the quotient of
`1.728*10^9 and, 4.8*10^6` expressed in scientific notation?

`(1.728*10^9)/(4.8*10^6)` Divide

`(1.728)/(4.8) * (10^9)/(10^6)` Divide numbers and 10's separately.

`0.36*10^3` Subtract exponents.

`(3.6*10^-^1 )*10^3` Rewrite as a number bigger than 1

`3.6*(10^-^1*10^3)` Associate

The answer is

`3.6*10^2` Add exponents

Answer 2

4.1386 X 10^3

Explanation:

since,

1.728 x 109 = 187 .48

4.8 X 106 = 0.04528 (approx. 0.0453)
