## Algebra 1: Common Core (15th Edition)

The sun is 3.51 $\times$ $10^{3}$ more massive than Saturn.
When you make the word problem into an equation you have, $\frac{1.998 * 10^3{^0}}{5.69 *10^2{^6}}$. The numerator represents the sun's mass and the denominator represents Saturn's mass: $\frac{1.998 * 10^3{^0}}{5.69 *10^2{^6}}$ -subtract the exponents- $10^{30-26}$=$10^{4}$ $\frac{1.998}{5.69}$ $\times$ $10^{4}$ -divide the terms- 0.351 $\times$ $10^{4}$ -change it into scientific notation form- =3.51 $\times$ $10^{3}$
