Question 75070
4/the square root of 7


{{{4/sqrt(7)}}}  First, multiply both numerator and denominator by {{{sqrt(7)}}}.  We can do this because {{{sqrt(7)/sqrt(7)=1}}} and this will get rid of the radical in the denominator


{{{(4sqrt(7))/(sqrt(7))(sqrt(7))}}} and this equals

{{{(4sqrt(7))/7}}}------------------ans
