Question

Answer 1

x	5	9	0,16	0,0625	9/4
\(\sqrt{x}\)	\(\sqrt{5}\)	3	0,4	0,25	3/2

 

Answer 2

Nhắc lại ta có như sau:

Nếu: \(x=a\)

\(\Rightarrow\sqrt{x}=\sqrt{a}\) 

Nếu: \(\sqrt{x}=a\)

\(\Rightarrow x=a^2\)

\(x\)	\(5\)	\(3^2=9\)	\(0,16\)	\(0,25^2=0,0625\)	\(\dfrac{9}{4}\)
\(\sqrt{x}\)	\(\sqrt{5}\)	\(3\)	\(\sqrt{0,16}=0,4\)	\(0,25\)	\(\sqrt{\dfrac{9}{4}}=\dfrac{3}{2}\)
