Question

please give answer fast and step by step​

Answer 1

GIVEn

2/2 - √3

Rationalize it

SOLUTIOn

→ 2/2 - √3

→ 2/2 - √3 × 2 + √3/2 + √3

★ Applying identity :

(a + b)(a - b) = a² - b²

→ 2(2 + √3)/(2)² - (√3)²

→ 4 + 2√3/4 - 3

→ 4 + 2√3

SOMe IDENTITIEs

• (a + b)² = a² + b² + 2ab
• (a - b)² = a² + b² - 2ab
• a³ + b³ = (a + b)(a² - ab + b²)
