Answer 1

Answer:

Step-by-step explanation:

Given that,

( 1 + 1/√2 + 1 ) ( 1 - 1/√2+ 1/2)

= ( √2 + 1 + √2 / √2) ( 2√2 - 2 + √2 / 2√2)

= ( 2√2 + 1 / √2) ( 3√2 - 2 / 2√2)

= [ ( 2√2 × 3√2 ) - (2√2 × 2)+ (1 × 3√2 ) - ( 1 × 2) ] / 2 (√2)² (∵ + × ' = ' )

= [ 6 (√2)² - 4√2 - 4∛√2 + 3√2 - 2 ] / 2 ( 2 )

= ( 6 ( 2) - 5√2 - 2 ) / 4

= ( 12 - 2 - 5√2 )/ 4

= (10 - 5√2) / 4 Is the answer.
