Răspuns:
(1/√2)^n
Explicație pas cu pas:
√2*(1/√2)^n=√2/√2^(n-1)= (√2/√2)/√2^n=1/√2^n
[tex]\it \sqrt2\cdot\Big(\dfrac{\sqrt2}{2}\Big)^{n-1}=\sqrt2\cdot\Big(\dfrac{\sqrt2}{2}\Big)^{n}\cdot\Big(\dfrac{\sqrt2}{2}\Big)^{-1}=\sqrt2\cdot\dfrac{2}{\sqrt2}\cdot\Big(\dfrac{\sqrt2}{2}\Big)^{n}=2\cdot\Big(\dfrac{\sqrt2}{2}\Big)^{n}[/tex]
