Hi there, it would be good to see what you have tried.

If you know the arrays are always going to have an equal number of elements, you can use the length to create a numeric range then loop through that range, using the numbers as indexes to get an element from each array.

for my $i ( 0 .. $#array1 ) {
    say join ' ', $array2[$i], $array1[$i];
}

There are a plethora of other ways, many more idiomatic. But this should get you started figuring out the concepts.

Hope that helps!
