Show working to simplify `a` and `b` such that  `a, b`  are real numbers and

`(8-sqrt27)/(2sqrt3) = a + bsqrt3`.   (2 marks)

Show Answers Only

`:. a =-3/2, \ b = 4/3`

Show Worked Solution
`(8-sqrt27)/(2sqrt3) xx (sqrt3)/(sqrt3)` `=(sqrt3(8-3sqrt3))/(2xx3)`
  `= (8sqrt3-9)/6`
  `= -3/2 + 4/3sqrt3`

 
`:. a = -3/2, \ b = 4/3`
