Answer 1

Step-by-step explanation:

1/3-√8×(3+√8)/(3+√8)

=3+√8/9-8

3+√8

based on the above process the remaining prblm is doing

(3+√8)-(√8+√7)+(√7+√6)-(√6+√5)+(√5+2)

=3+√8-√8-√7+√7+√6-√6-√5+√5+2

=3+2=5

Answer 2

$\frac{1 \times 3 + \sqrt{8} }{3 - \sqrt{8} \times 3 + \sqrt{8} } = \frac{3 + \sqrt{8} }{ {3}^{2} - \sqrt{ {(8)}^{2} } } = 3 + \sqrt{8}$

similarly

3+√8-(√8+√7)+√7+√6-(√6+√5)+√5+2

=3+2

=5
