Question 190074: I am having trouble with a word problem. Here it is:
What is the smallest counting number n so that the
square root of 2n is a multiple of 3?
I think the answer is 18 but I do not know how to show all work.
I think the square root of 2n has to be divisible by 3 but it also
has to be divisible by 2. 6 would be the smallest divisible by 2 and 3.
Thanks. JCE
