Answer 1

Answer:

The conjucate of (9 + 5–√ + 6–√) is (9 - (5–√ + 6–√))

= 19+5√+6√ x 9−(5√+6√)9−(5√+6√)

= 9−(5√+6√)92−(5√+6√)2

= 9−(5√+6√)81−(5+6+230√)

= 9−(5√+6√)70−230√

Stage 2: The conjucate of (70 - 230−−√) is (70 + 230−−√)

9−(5√+6√)70−230√ x 70+230√70+230√

= 630+1830√−705√−106√−706√−125√4900−120

= 630+1830√−825√−806√4780
