when i type

1.1-\dfrac{3\times \sqrt 1.1 + \frac{18}{\sqrt 1.1} -20}{\frac{3}{2} \times 1.1^{-\frac{1}{2}} -9\times 1.1^{-\frac{3}{2}}}


in my calculator it doesn't work and give me and answer of 1.140787458 to 9 d.p

but when i type in 3\times \sqrt 1.1 +\dfrac{18}{\sqrt 1.1} -20=A

and \dfrac{3}[2} \times 1.1^{-\frac{1}{2}} -9\times 1.1^{-\frac{3}{2}}=B

and then 1.1-\dfrac{A}{B} i get 1.148463312 to 9 d.p but to 3d.p is 1.15 the correct answer, what is wrong?

Then you're typing it in wrong. Probably getting confused between the indices or something.
