Question 412345
{{{(Mass of the Sun)/(Mass of Saturn)}}}
-
First just leave the {{{10^x}}} part alone.
Divide 1.988 by 5.688
{{{1.998=5.688=0.3512}}} (approximate)
-
Now looking back at the exponents, {{{10^27}}} and {{{10^23}}}
When you divide these, since they have the same base (10), you can simply subtract the exponents.  (27-23) = 4.  {{{10^4}}}
- 
Combining the two parts you get {{{0.3512*10^4}}}
-
Scientific notation has 1 non zero digit before the decimal.  {{{3.512*10^3}}}  When you move the decimal to the right, that is like multiplying the number by 10.  Since you are multiplying by {{{10^4}}}, you can simply divide by 10, aka {{{10^1}}}, which simplifies to {{{10^3}}}

Answer:
{{{highlight(3.512*10^3)}}}
