Thread: One more logarithm equation ><

log(x-73)+log(x-88)+2

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
