Question 135825
It's a general rule that {{{sqrt(a)/sqrt(b) = sqrt(a/b)}}}
{{{sqrt(75)/sqrt(3) = sqrt(75/3)}}}
Do the division first
{{{75/3 = 25}}}
{{{sqrt(75/3) = sqrt(25)}}}
{{{sqrt(25) = 5}}}
{{{sqrt(25) = -5}}}
------------------
Note that {{{5*5 = 25}}}
and
{{{(-5)*(-5) = 25}}}
That's why there are two square roots of 25
