Question

RATIONALISE THE DENOMINATOR ROOT 3 - ROOT 2 UPON ROOT 3 - ROOT 2

Answer 1

Answer:

Step-by-step explanation:

( √3 + √2 ) / ( √3 - √2 )

= [ (√3+√2)(√3+√2)]/[√3-√2)(√3+√2)]

= ( √3 + √2 )² / [ ( √3 )² - ( √2 )² ]

= [ (√3)² + ( √2)²+2×√3×√2 ] /( 3 - 2 )

[ By using ( a + b )² = a² + b² + 2ab ]

= ( 3 + 2 + 2√6 ) / 1

= 5 + 2√6
