Step-by-step explanation:

Step below are self-explanatory

  • 2/(√3−1)=
  • 2×(√3 + 1)/(√3 - 1)×(√3 + 1) =    multiplied both sides by √3 + 1
  • 2×(√3 + 1)/(√3² - 1²)=               used (a+b)(a-b)= a² - b² formula
  • 2×(√3 + 1)/(3 - 1)=
  • 2×(√3 + 1)/2=                            cancelled like terms
  • √3 + 1
