Question

the mass of earth is about 5.97 x 10^24 kilograms and the mass of pluto is about 1.3 x 10^22 kilograms. the difference in the mass of earth and pluto is kilograms.
5.983 × 10^24
7.27 × 10^24
5.957 × 10^24
4.67 × 10^24

Explanation:

Step1: Rewrite Pluto's mass in same exponent form

We rewrite the mass of Pluto $1.3\times 10^{22}$ as $0.013\times 10^{24}$ (since $1.3\times10^{22}=1.3\times\frac{10^{24}}{10^{2}} = 0.013\times 10^{24}$).

Step2: Subtract the masses

Subtract the mass of Pluto from the mass of Earth: $(5.97 - 0.013)\times10^{24}$.
$5.97- 0.013=5.957$. So the result is $5.957\times 10^{24}$.

Answer:

$5.957\times 10^{24}$
