A review question I'm not sure how to answer, the question says to add or subtract whenever possible and to simplify the answer.

You need to find square numbers inside the square root i.e 1,4,9,16,25,36,... to help simplify.
Now do the same for the first term and finish.
but what happens with the 3 and 4, I multiply them with the 6 and 5?
oh wait, i got the answer
thank you so much
