27/189=X/(1-X)
(30-2x)(20-2x)=400
189/27=X/(1-X)
128.9=X*(1-X^60)/(1-X)
189/27=1/(1-X)
X^2+12100=220X
3/2x+6≤4+7/2x
129.9X-128.9-X^61=0
-90+arctan(x/4.8)-arctan(0.2x)-arctan(0.0625x)-arctan(x/115.2)=-180
100000(1+x/2)^8=214358. 88
129.9X-128.9-X=0
455-929500000000
x/(0.0462-x)/(0.1346-2x)^2=1.26*10^21
3=lgx
90+arctan(23.5/4.8)-arctan(0.2*23.5)-arctan(0.0625*23.5)-arctan(23.5/115.2)=x
2*130*10^6/1.0*14.3*250
90+arctan(23.5/4.8)-arctan(0.2*23.5)-arctan(0.0625*23.5)-arctan(23.5/115.2)
x/5=1
40000 = x^2(0.04x^2+1)((0.0625x)^2+1)
150000x^2-160000x^4=2500-10000x
