Point a has coordinates (7,2). Point b has coordinates (2,-10). Find the coordinates of point P that partition AB into ratio 5:1

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.

(-0, -7) is your answer
