Question

plz answer fast its argent ata ho tavi dena​

Answer 1

1) B

==> 36/45 = 4/5

Denominator = 5

And It can represented in the form of 2^m × 2^n

2) A

3 ) B

$= = > \: \: \frac{8 - \sqrt{8} }{8 + \sqrt{8} } \\ \\ = = > \: \: \frac{8 - \sqrt{8} }{8 + \sqrt{8} } \times \frac{8 - \sqrt{8} }{8 - \sqrt{8} } \\ \\ = = > \: \: \frac{ {(8 - \sqrt{8}) }^{2} }{64 - 8} \\ \\ = = > \: \: \frac{64 + 8 - 2 \sqrt{8} }{56} \\ \\ = = > \: \: \frac{72 - 4 \sqrt{2} }{56} \\ \\ = = > \: \: \frac{18 - \sqrt{2} }{14}$

4) B

5) A

x = 0.695695...

1000x = 695.695695...

999x = 695

==> x = 695/999

6 ) A

==> 56 / 80

Can also be written as

==> 28/40

==> 14/20

Denominator = 20

==> 20 = 5 × 2²

Which is expressed in the form 2^m × 2^n And hence is a terminating decimal.
