=2√3+2 ÷ (√3)² -1²
=2√3+2 ÷ 3-1
=2√3+2 ÷ 2
2. 2+√3 ÷ 2-√3 × 2+√3 ÷ 2+√3
=4 + 2√3 + 2√3 + 3 ÷ 2² + √3²

Answer:
1. √3 +1 / 1 or √3 + 2 2. 7 + 4√3 / 1 or 7 + 4√3
Step-by-step explanation:
1. 2/ √3 -1
⇒ 2 / √3 - 1 * √3 + 1 /√3 -1
⇒ 2√3 + 2 / (√3)^2 - (1)^2
⇒ 2√3 +2 / 2 → √3 + 1 / 1
2. 2 + √3 / 2 - √3
⇒ 2 + √3 / 2 - √3 * 2 + √3 / 2 + √3
⇒ ( 2 + √3) ^2 / (2 ) ^2 - (√3) ^2
⇒ 4 + 3 + 4√3 / 4 -3 → 7 +√3 / 1
