Question

1 by √9-√8-1 by √8-√7​

Answer 1

Answer:

by rationalizing each number, you get:-

\sqrt{9} + \sqrt{8} - \sqrt{8} + \sqrt{7} - \sqrt{7} + \sqrt{6} - \sqrt{6} + \sqrt{5} - \sqrt{5} + \sqrt{4}

9 + 8 −8 + 7 − 7 + 6 −6+ 5 − 5 + 4

after evaluating it, you get

\sqrt{9} + \sqrt{4}

9 + 4which is:-

3 + 2

= 5
