the qoutient rule of radicals
Answered
hi
Is the domain of sqrt(f/g) = the domain of sqrt(f)/sqrt(g)
while sqrt(a/b)=sqrt(a)/sqrt(b)
asking this question because of the limit of sqrt(x^21)/sqrt(x1) when x goes to 1 =sqrt(2)
while in the 2nd case does not exists,
as teachers how can we convince our students not to apply the cautient rule of radicals when they taking the limits.

hello
when i read f(x)=g(x) i think the writer meant f(x)=g(x) for x in domain(f) intersected domain(g)
so log(a*b)=log(a)+log(b)
saludos
hello
of course when a*b>0
most of the rules are true in the positive numbers only
saludos
Thank you ,
