Question 412345: NEED HELP WITH THIS PROBLEM ASAP! THANKS IN ADVACNED!!!!
Bridget

The mass of the saturn is about 5.688X10 23(the number 23 is supposed to be above the 10) metric tons. The mass of the sun is about 1.998X10 27 (the 27 is supposed to be above the 10) metric tons. About how many times the mass of Saturn is the mass of the sun? Give your answer in scientific notation.

First just leave the 10%5Ex part alone.
Divide 1.988 by 5.688
1.998=5.688=0.3512 (approximate)
-
Now looking back at the exponents, 10%5E27 and 10%5E23
When you divide these, since they have the same base (10), you can simply subtract the exponents. (27-23) = 4. 10%5E4
-
Combining the two parts you get 0.3512%2A10%5E4
-
Scientific notation has 1 non zero digit before the decimal. 3.512%2A10%5E3 When you move the decimal to the right, that is like multiplying the number by 10. Since you are multiplying by 10%5E4, you can simply divide by 10, aka 10%5E1, which simplifies to 10%5E3
