sqrt(1240/c)=3963
---
square both sides to get:
(1240/c) = 3963^2
---------------
c = 1240/3963^2
---
c = 7.8954^10^-5
--------------------------
Checking:
sqrt[(1240/(1240/3963^2)] = 3963
-----------
[(1240/(1240/3963^2)] = 3963^2
-----
(1240) = [1240/3963^2][3963^2]
1240 = 1240

Answer by jerryguo41(197) (Show Source): You can put this solution on YOUR website!
square both sides
multiply c to both sides
Divide 3963^2 from both sides
thus if you plug in
sqrt(1240/(1240/15705369))
in a calculator you will get 3963
