Question: Numerical explicit solving RootOF

I have that problem that I am trying to solve the following equation explicit:

TY = RootOf(6.750969101*10^26*_Z*1000^(9/59)*800^(41/59)-1.015701668*10^27*1000^(50/59)-1.189275761*10^27*800^(50/59)+1.103397224*10^26*_Z*1000^(32/59)*800^(18/59)-7.457053114*10^23*3^(1/5)*1000^(41/59)*800^(50/59)*_Z^(4/5)*sqrt(12500)*4^(19/20)*(800^(9/59)+1000^(9/59))^(1/50)*(702.222720*1000^(9/59)+976.508160*800^(9/59))^(4/5)-7.457053114*10^23*3^(1/5)*1000^(50/59)*800^(41/59)*_Z^(4/5)*sqrt(12500)*4^(19/20)*(800^(9/59)+1000^(9/59))^(1/50)*(702.222720*1000^(9/59)+976.508160*800^(9/59))^(4/5)-1.988547497*10^26*3^(1/5)*1000^(32/59)*_Z^(4/5)*sqrt(12500)*4^(19/20)*(800^(9/59)+1000^(9/59))^(1/50)*(702.222720*1000^(9/59)+976.508160*800^(9/59))^(4/5)-2.485684371*10^26*3^(1/5)*800^(32/59)*_Z^(4/5)*sqrt(12500)*4^(19/20)*(800^(9/59)+1000^(9/59))^(1/50)*(702.222720*1000^(9/59)+976.508160*800^(9/59))^(4/5)+5.575397080*10^26*_Z*1000^(41/59)*800^(9/59)+1.308382216*10^26*_Z*1000^(18/59)*800^(32/59)+1.378754484*10^27*_Z*800^(50/59)+1.114796623*10^27*_Z*1000^(50/59)-1.144263788*10^26*1000^(32/59)*800^(18/59)-1.028573111*10^26*1000^(18/59)*800^(32/59)-5.399913635*10^26*1000^(41/59)*800^(9/59)-5.544622178*10^26*1000^(9/59)*800^(41/59))

It looks quite complicate but there are no variables left. The result should be a value for TY.

I tried a lot to get rid of _Z, for example evlaf(), remove_RootOf(), allvalues()...

Has anyone an idea how I get my result?

Thanks
