Please give me right answer.​

Answer 1

${ \huge{ \color{pink}{ \underline{ \underline{ \sf{ \color{aqua}{คຖŞຟēr}}}}}}}$

$\large( \frac{21}{20} {)}^{ \frac{1}{2} } = \frac{21 \frac{1}{2} }{20 \frac{1}{2} } = \frac{ \sqrt{21} }{ \sqrt{20} } = \frac{4.58}{4.47}$

${\large { \color{aqua} {\boxed{ \color{pink}{\sf {❥Hope \: it \: helps \: you....}}}}}}$
