\[6-3\sqrt{2}\] is the equation
OpenStudy (anonymous):
(6-3sqrt2)(6+3sqrt2)... should give you 54
OpenStudy (anonymous):
I'm sorry I was wrong. It is 18... Since the conjugate causes the last terms to be negative.
OpenStudy (anonymous):
Yes, I figured it was 18. Just did the calculations thank you for your help! :)
OpenStudy (anonymous):

Would you happen to know the answer to this one 3 square root of 15 lies between two consecutive integers. What would the two consecutive integers be?
OpenStudy (anonymous):
Yeah. Your result is 11.61. So your two integers would be 11 and 12

|dw:1319495473653:dw|\[\sqrt[3]{15}\]
OpenStudy (anonymous):
is it 3 times root 15 or the 3rd root of 15
OpenStudy (anonymous):

oh ok, then your answer is 2.466 so your two integers would be 2 and 3
