Question
how do you simplify square root of 27 minus square root of 49 all divided by square root of 3. I have gotten two different answers when I tried to check it. It kind of looks like (27-49)
(3)
except all the numbers have their own square root symbol. I don't know if it will be lined up when I post the question

Answers
do you mean
(√27 - √49)/√3 ??
if so then
= (3√3 - 7)/ 2√3
now if you want to rationalize that, multiply top and bottom by √3 to get
(9 - 7√3)/3

Where did you get the 2 from in the second part of your solution?
