Question 1073219
{{{log(10,(x+2))}}}


Powers of 10 are not complicated, using whole numbers especially.  


Look at the result, y, in trying each x of the listed choices.


{{{10^y=8+2}}}
{{{10^y=10}}}
You KNOW y=1.
Choice a works, being the point  (8,1).  


You have three more choices to look at.  Do any of them also work?


ADDITIONAL NOTE:  You do not need any kind of hand-held calculator to do this problem.
