Answer:
1) ( 10 - 6√5 ) / 10
2) ( 20√3 - 3√5 + 30√2 ) / 15
Step-by-step explanation:
1) 1/2 + √3 + 2/√5 - √3 + 1/2 - √5
= 1/2 + 2/√5 + 1/2 - √5
= 1/2 + 1/2 - √5 + ( 2/√5 × √5/√5 )
= 1/2 + 1/2 - √5 + 2√5/5
= 5/10 + 5/10 - 10√5/10 + 4√5/10
= 10/10 - 6√5/10
= ( 10 - 6√5 ) / 10
2) 2/√5 + √3 + 1/√3 + √2 - 3/√5 + √2
= -1/√5 + √3 + 1/√3 + 2√2
= ( -1/√5 × √5/√5 ) + √3 + ( 1/√3 × √3/√3 ) + 2√2
= -√5/5 + √3 + √3/3 + 2√2
= -3√5/15 + 15√3/15 + 5√3/15 + 30√2/15
= -3√5/15 + 20√3/15 + 30√2/15
= ( 20√3 - 3√5 + 30√2 ) / 15
