Question

Calculati :
√2·√2/2-(1/2+1/2)≈

Answer 1

$\sqrt{2} \times \frac{ \sqrt{2} }{2} - ( \frac{1}{2} + \frac{1}{2}) = \sqrt{2} \times \frac{ \sqrt{2} }{2} - 1 = \frac{ \sqrt{2} \sqrt{2} }{2} - 1 = \frac{ \sqrt{4} }{2} - 1 = \frac{2}{2} - 1 = 1 - 1 = 0$

Answer 2

√2·√2/2-(1/2+1/2) =

= √4/2 - 1

= 2/2 - 1

= 1 - 1

= 0
