It's so simple the equivalent resistance on primary side = r2*a*a,
So, 2000*(1/5)*1/5 = 80.
So, 2000*(1/5)*1/5 = 80.

What's the meaning of (n2/n1)=(r2/r1)^0.5 ?
What is (^) in this statement?

(n2/n1)=(r2/r1)^0.5
(v2/v1)=(r2/r1)^0.5
(5)=(2000/r1)^0.5
r1=2000/25
=80
(v2/v1)=(r2/r1)^0.5
(5)=(2000/r1)^0.5
r1=2000/25
=80

n2/n1= (r2/r1) only.
I do not understand how you get.
