Question 176975
When they are asking you to write it in "rational" form, they do not want to see any radicals (square root symbols) in the denominator.
.
{{{5/(sqrt(2)+ sqrt(3))}}}
.
Multiply by the above by: {{{(sqrt(2)- sqrt(3))/(sqrt(2)- sqrt(3))}}}
.
{{{5(sqrt(2)- sqrt(3))/((sqrt(2)+ sqrt(3))(sqrt(2)- sqrt(3)))}}}
.
{{{5(sqrt(2)- sqrt(3))/(2 - 3))}}}
.
{{{5(sqrt(2)- sqrt(3))/(-1)}}}
.
{{{5(sqrt(3)- sqrt(2))}}}
.
or,
{{{5sqrt(3)- 5sqrt(2)}}}
