알아보다 is actively finding something out — researching, checking, asking around. Half of these lines pair it with ~에 대해서 ('about ~'), and ~에 대해서 알아보도록 하겠습니다 is the standard opener for an explainer video, roughly 'let's take a look at ~'. Other lines show the -어서 clause as a preceding act instead: 가서 알아보셔야 돼요 (you have to go and find out). A second sense of 알아보다, recognising something by sight, is what 봐서 알아볼 정도 uses.
