135 in Roman numerals is CXXXV
135 = CXXXV
The positional place value of these numerals are incorrect so they wouldn't stand for anything. But if they were arranged as: llxxxv this would mean 50+50+10+10+10+5 = 135 which in Roman numerals would be simplified to CXXXV.
You really can't, as I don't want to be here all day typing M's, but it would be M with a line over it (x9542) C with a line over it, D with a line over it, L with a line over it, X with a line over it (x48), CXXXV.

XXVII = 27. XXVII squared = XXVII(X+X+V+I+I) = 27(10+10+5+1+1). Multiplying out the brackets = CCLXX+CCLXX+CXXXV+XXVII+XXVII = 270+270+135+27+27. When summed up = DCCXXVIIII = 729 or IDCCXXX = 730-1 but not as DCCXXIX. Numerical values: M=1000, D=500, C=100, L=50, X=10, V=5, I=1.
The above equivalent numbers added up in Roman numerals are as follows:- XVI+XVII = XXXIII (16+17 = 33) XXXIII+XXVI = LVIIII (33+26 = 59) LVIIII+XXVIII = LXXXVII (59+28 = 87) LXXXVII+CXXXV = CCXXII (87+135 = 222) The Romans would have used an abacus counting device to add up these numerals which avoids writing them all out in full because when the numerals are keyed into the device by means of moveable beads it would come up with a final figure of CCXXII
