Simplify.
Remove all perfect squares from inside the square roots. Assume y and z are positive.
√75yz^2

Step-by-step explanation:

First, you can break it up:   sqrt 75,  sqrt y,  sqrt z^2

Then, you can sq root all of it:

- sqrt z^2 is just z

- sqrt y stays the same

- sqrt 75 can be broken into sqrt 25 * sqrt3

           - That would equal to 5 sqrt 3

After all that, combine everything:

5z sqrt 3y

d is correct
