I checked the answer and it says [ATTACH=full]4129[/ATTACH]

I don't really understand this.
Can anyone explain this to me? I couldn't find any online videos to help me understand this either.

I do know how to convert from index form to logarithmic form and simplify logarithmic expressions, solve some logarithmic equations. I don't get how to sketch the graph to find the answer in these 2 questions though.
