Subject: sqrt equation 5sqrt2 - 10sqrt2 +12/3 easy enough, 5sqrt2 +3 but 2+3 or 5 meet the criteria for simplifying a sqrt??? I don't understand why 5sqrt2+3 is the correct answer over 5sqrt 5 thanks for the help in advance |
Hi Mike,
I think the confusion here is between sqrt(2 + 3) and sqrt 2 + 3 = (sqrt2) + 3.
Sqrt(2 + 3) is of course sqrt5 but (sqrt2) + 3is not.
