Question 938692
" Given that 2744 dived by N " IS a perfect square, find the value(s) of N. 
-----------------
Factor 2744
--- 
2744 = 2*2*2*7*7*7
Then pick any combinations of the 6 factors that have and even # of 2's and 7's (including 0).
--> 2*2*7*7 = 196
N = 14
--> 7*7 = 49
N = 56
--> 2*2 = 4
N = 686
---
Also N = 2744
======================
N = 2744*4 --> 1/4, a perfect square if you allow fractions.
