2) Dallas Palmeri rented an SUV with 150 free miles and $0.25 each additional mile for $62.93 per day. Dallas rented the

Maybe the answer is 20mm. all i really did was just multiply, which is obvious.

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.
