X=1.05×(1/X^0.66)^(-0.35)
x=1.05 * (1/(x^0.66)^(-0.35)
x=1.05 * (x^(-0.66))^(-0.35)
x=1.05 * x^((-0.66)*(-0.35))
x=1.05 * x^(0.231)
1=1.05 * x^(0.231)*x^(-1)
1=1.05 * x^(0.231-1)
1=1.05 * x^(-0.769)
1/1.05 = x^(-0.769)
log(1/1.05) = -0.769*log(x)
log(x)=-(log(1/1.05))/0.769
x= 10^(-(log(1/1.05))/0.769)
大変ありがとうございます。
