Question

2/√5 given value √2=1.414,√5=2.236​

Answer 1

$heya \: ....... \\ \\ \frac{ {2} }{ \sqrt{5} } = \frac{2}{2.236} \\ \\ = \geqslant \frac{1}{1.118}$

Answer 2

Answer -

$\sf \frac{2}{ \sqrt{5}} \times \frac{ \sqrt{5} }{ \sqrt{5} } \\ \\ \frac{2 \times \sqrt{5} }{( \sqrt{5}) {}^{2} } \\ \\ \frac{2 \sqrt{5} }{5}$

Given that,

√2 = 1.414

√5 = 2.236

$\frac{2 \sqrt{5} }{5} \\ \\ \frac{2 \times 2.236}{5} \\ \\ \frac{4.472}{5} \\ \\ = 0.8944$
