There is a wrong understanding in your post.

Numbers exist independently of their (hexadecimal, decimal or other) representations.

From Perldoc: hex interprets EXPR as a hex string and returns the corresponding value.

The hex function converts a string into a number, it does not convert an hex number into a decimal number (even though if you print the output of hex, it will be printed as a decimal number, this does not imply that they're stored as decimal numbers, as this is irrelevant, they are stored as numbers).

Now, if you want to multiply numbers, they have some how to be numbers. So you need to convert your strings into numbers (not decimal or hexadecimal numbers), or at least something that Perl understands as numbers. So converting your hexadecimal strings to numbers is the right way to do it. And, once you've done that, you can multiply your numbers, and then print out the resulting number value in any representation you wish, including hexadecimal representation or any other one.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

• Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
• Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
• Read Where should I post X? if you're not absolutely sure you're posting in the right place.
• Posts may use any of the Perl Monks Approved HTML tags:
a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
• You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
 For: Use: & & < < > > [ [ ] ]
• Link using PerlMonks shortcuts! What shortcuts can I use for linking?
