A question that really stumped me was in the practice test, question number 15 the question was:

This question really confused me because I wasn’t use to solving radicals with variables, so this threw me of and I really didn’t even know where to start, at first I tried isolating the variable by getting “x”, “y”, and “z” by themselves because I knew that I have to figure out what the value of the variables were, but the more I tried to solve it the more confusing it got because I was getting decimals for answers. I soon realised that there were two parts the each equation, For Example: the first equation, there were two radicals that are equal but one just has a variable, because one of the radicals were complete and a mixed radical I made the mixed radical into a entire radical to figure out what ”x” was, and now that I had ”x” I substituted “x” in the second equation and turned the mixed radical into a entire radical and then divided the entire radical by the radicand of the second mixed radical, then square rooted that answer to find “y” and I did the same thing that I did to find “y” to find “z”.
