You can put this solution on YOUR website!
Y=R+p^2KL/A ;solve for K
:
y = R + %28p%5E2KL%29%2FA
multiply both sides by A
yA = RA + p^2KL
Subtract RA from both sides
yA - RA = p^2KL
Divide both sides by p^2L
%28%28yA-RA%29%29%2F%28%28p%5E2L%29%29 = K

Y=R+p^2KL/A ;solve for K
subtract R from both sides of =
p^(2KL/A) = Y-R
==============================================
now use definition of logarithm
2KL/A = log(p)(Y-R)
multiply both sides of = by A
2KL = A*log(p)(Y-R)
divide both sides of = by 2L
K = A*(log(p)(Y-R)) / 2L
