 Question 264925: hello,im homeschooled and i had a problem solving this expression. can you please check it for me here it is: square root(18)-square root(3)/square root(6) my answer was: square root(3)-square root(1/2) is this right or can i simplify it more? and also my textbook did not explain these kind of problems very well: square root(a)+square root(b)/square root (a)-square root(b) this one is also similar to it: square root (5)+1/square root(5)-1 THANK YOU FOR ANSWERING!!!
