Translation:Please help me.
助 means the same as 帮 (in this instance), 'help' or 'to help'. similar characters are often paired together for emphasis, or when alone they might have several meanings. 助 is only help, but 帮 can have several meanings depending on context
Context matters. For a specific task or aid, 帮忙 may be better.
帮助 is transitive, i.e. it need a receiver. We do not say 我也帮助, as it is not complete and sounds like “I also help …”. Instead we say 我也帮忙 “I (will) also help.”
帮忙 is intransitive, i.e. it does not need a receiver. Do not say 我帮忙你 (shoud say 我帮助你 or 我帮你(的)忙). Do not say 我帮助工作 (should say 我帮忙工作 “I help to work.”).
