Two students are passing a ball back and forth, allowing it to bounce once between them. If one student bounce-passes the ball from a height of 1.6 meters and it bounces 3.2 meters away from the student,
where should the second student stand to catch the ball at a height of 1.5 meters? Round your answer to
two decimal places, if necessary.

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.
