By applying the concept of multiplication, we determine that Marcus walks his dog a total of 3.6 miles in 6 days if he walks 3/5 of a mile each day.
This question actually involves simple mathematics, specifically the concept of multiplication. Since Marcus walks his dog 3/5 of a mile each day, in order to calculate how far Marcus walks his dog in 6 days, we simply multiply the daily distance by the number of days. Therefore, the calculation will be as follows: 3/5 mile/day * 6 days = 18/5 miles = 3.6 miles.
So, Marcus walks his dog a total of 3.6 miles in 6 days.

First you would simplify what's in the square root, to get root 20. If you want the exact number, and not the approximation, you would take out whatever squares are in that number (20=2*2*5) so your answer is 2root5.
However, if you want the approximation, simply plug it into your calculator and get 4.18154055.
