Question 149989
The idea here, is to get rid of the square root sign from the denominator.
.
Starting with:
(2)/(5 - {{{ sqrt( 3 ) }}})
Multiply numerator and denominator by (5 + {{{ sqrt( 3 ) }}})
.
(2)/(5 - {{{ sqrt( 3 ) }}}) * (5 + {{{ sqrt( 3 ) }}})/(5 + {{{ sqrt( 3 ) }}})
.
Resulting in:
2(5 + {{{ sqrt( 3 ) }}})/ (25-3)
2(5 + {{{ sqrt( 3 ) }}})/ (22)
(5 + {{{ sqrt( 3 ) }}})/ 11
