Motorcycle rider travels at an average speed greater than 50 miles per hour. Identify an inequality that can be used to determine how many hours $t$ it will take the motorcycle rider to travel 375 miles. $50t>375$

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.
