    Lightbulb Check it out

    log(x-73)+log(x-88)=2
    2=log 100 (base is 10)
    log(x-73)+log(x-88)=log100
    as loga+logb=logab therfor
    log(x-73)(x-88)=log100
    or (x-73)(x-88)=100
    solving them we get
    x=93 and x=64
    we ignore 64 as its out of domain so the final answer is x=93
