Answer 1

3)

4√3 + 7√5 – 2√3 – 3√5

a) 2√3 + 4√5 is the correct answer

4)

( 1 + √35 ) ( 1 – √35 )

1 – 35

– 34

c) negative integer is the correct answer

Answer 2

Step-by-step explanation:

$(4 \sqrt{3} + 7 \sqrt{5} ) - (2 \sqrt{3} + 3 \sqrt{5} ) = 4 \sqrt{3} + 7 \sqrt{5} - 2 \sqrt{3} - 3 \sqrt{5} = 2 \sqrt{3} + 4 \sqrt{5}$

So a part is answer.

$(1 - \sqrt{35} )(1 + \sqrt{35} ) = {1}^{2} - { \sqrt{35} }^{2} = 1 - 35 = ( - 34)$

Using the property a2-b2=(a+b)(a-b)

So answer is c part

Hope this helps......
