" Given that 2744 dived by N " IS a perfect square, find the value(s) of N.
OH no!! What should I do?! Found 3 solutions by LinnW, Alan3354, MathLover1:Answer by LinnW(1048) (Show Source):
You can put this solution on YOUR website! = perfect square
There must be at least one n such that = for the first statement to be true
So, =
Using cross products, = 2744 and
N =
Factoring 2744 gives us 2*19*73
For N to be an integer ( required to be a perfect square ) ,
n^2 must divide into 2*19*73 without remainder.
For this to be true, there need to be at least two duplicate
integers in the numerator.
This means that there does not exist an integer N
such that is a perfect square.

-----------------
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.
