Zadanko dla relaksu :)

Oblicz:

[tex]\sqrt\sqrt{16} =[/tex]
[tex]\sqrt{\sqrt{81}}-\sqrt{\sqrt{625} }=[/tex]
[tex]\sqrt\sqrt{36}-2}=[/tex]
[tex]\sqrt{8+\sqrt{64} } =[/tex]
[tex]2\sqrt{3*\sqrt{9}}=[/tex]


Odpowiedź :

√√16= √√4² = √4 = √2² = 2

√√81 - √√625 = √√9² - √√25² =

= √9 - √25 = √3² - √5² = 3 - 5 = - 2

√(√36 - 2) = √(√6² - 2) = √(6 - 2) =

= √4 = √2² = 2

√(8 +√64) = √(8 +√8² ) = √(8 + 8) =

= √16 = √4² = 4

2√(3×√9) = 2√(3×√3²) = 2√(3×3) =

= 2√9 = 2√3² = 2× 3 = 6
