That backslash has no function in single quotes, it is included literally
in your string. Print out "$first" before the substitution to see it.

Since your substitution does nothing about a literal backslash, it stays in.
You don't want to "ignore" the backslash, you don't want to put it in the
original string in the first place.
my $first ='${string1} &';
