'i light my bombs with much force' is the definition.
I can't tell whether this definition defines the answer.

'i light my bombs' is the wordplay.
'bombs' is an anagram indicator.
'i'+'light'+'my'='ilightmy'
'ilightmy' with letters rearranged gives 'MIGHTILY'.

Can you help me to learn more?

(Another definition for mightily that I've seen is " To a very great extent".)
