If 9x9=29, what's the square root of 69 ?

Your one-line program must be as short as possible (least number of characters), must do the required calculations (not simply print the answer right away) and must output the shortest possible answer, one byte is better than eight and one nibble is better than one byte.

Hello Valentín,

First of all, welcome back!

1 CHR$(SQRT((9*9-9)/2*6+9)+55) ENDLINE will produce a one-line HP-71B program which upon run will give a one-character answer. Not sure wheter this will count as a valid solution to your micro-challenge though.

Best regards,

Gerson.
