Answer:
3= (3^25)
4= (2 x 10^6)
Explanation:
3. You would use the formula distance= rate x time
3^13 mph= rate 3^12 hours= time
When multiplying exponents with the same base you add the exponents.
3^13 * 3^12 = 3^(13+12) = 3^25
4. The easiest way to solve this problem is to divide using scientific notation.
First, convert 10 x 10^9 into scientific notation.= 1 x 10^10
Then, write the ratio of 1 x 10^10 to 5 x 10 ^3.
Divide the coefficients and subtract the exponents.
1 x 10^10
5 x 10 ^3
1/5= 0.2
10-3= 7
0.2 x 10^7
Convert to scientific notation.
2 x 10^6
