rewrite as equivalent rational expressions with denominator (3x−8)(x−5)(x−3). 4/3x2−23x+40,9x/3x2−17x+24

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.
