this is rationalise the surd
(2√11) / (√3 - 4)
= (2√11) / (√3 - 4) x 1
= (2√11) / (√3 - 4) x (√3 + 4) / (√3 + 4)
= (2√11) x (√3 + 4) / (3 - 16)
= (2√11) x (√3 + 4) / (-13)
= - (2√11)(√3 + 4)/13
(2√11) / (√3 - 4)
= (2√11) / (√3 - 4) x 1
= (2√11) / (√3 - 4) x (√3 + 4) / (√3 + 4)
= (2√11) x (√3 + 4) / (3 - 16)
= (2√11) x (√3 + 4) / (-13)
= - (2√11)(√3 + 4)/13
