Question

so sánh -5 và -√29

Answer 1

`-5=-\sqrt(5^2)=-\sqrt25`

`-\sqrt29=-\sqrt29`

Vì `25<29`

`=> \sqrt25<\sqrt29`

`=> -\sqrt25 > -\sqrt29`

`=> -5 > -\sqrt29`

Answer 2

Vì \(25< 29\Rightarrow\sqrt{25}< \sqrt{29}\Rightarrow5< \sqrt{29}\Rightarrow-5>-\sqrt{29}\)

Answer 3

\(25< 29\\ \Leftrightarrow\sqrt{25}< \sqrt{29}\\ \Leftrightarrow-\sqrt{25}>-\sqrt{29}\\ \Leftrightarrow-5>-\sqrt{29}\)

Answer 4

\(5=\sqrt{25}\)

mà 25<29

nên \(5< \sqrt{29}\)

\(\Leftrightarrow-5>-\sqrt{29}\)
