Please help me to solve this issue.

While the root-function as suggested by Fred is more compact and may be preferable in this case, I just wanted to point out the two errors you made:

1) Your guess value is missing a length unit

2) You had a typo in "find(an)" - there was an superfluous dot after the "n". Probably because you were used from MC15 to get the literal subscript by typing just a dot instead oft he more elaborate "Ctrl -".

P.S.: You sure know that "Given" is not recognized any more by Prime as being the start of a block and so this part is obsolete:

I only have Prime Express, so I can't check the operation of your solve block.  I can use the "root" function to solve your problem:

And I think if we assign units and use "Find" instead of "find", the solve block should work too.  Attached
