Royce walks 3/4 mile to school and 3/4 mile home each day. in how many days will he have walked 3 miles
i need the answer explained to me !

First, you would add 3/4+3/4 to see how many miles he walks each day. To get this you would simply add the numerators because the denominators are the same. This would get you to 3/4+3/4=6/4 You can then turn this fraction into a mixed number (1 2/4) which can be simplified into 1 1/2. He walks 1 1/2 miles one day and the second day he walks 1 1/2 miles. Add the two days together to get that in 2 days he walks 3 miles. 

The final answer is 2 days. I hope I helped :)

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
