a)
[tex] \sqrt{16} + \sqrt{25} = 4 + 5 = 9 [/tex]
b)
[tex] \sqrt{9} - \sqrt{4} - \sqrt{0} = 3 - 2 - 0 = 1[/tex]
c)
[tex] \sqrt{81} - \sqrt{100} + 2 \times \sqrt{4} = 9 - 10 + 2 \times 2 = - 1 + 4 = 3[/tex]
d)
[tex] - ( \sqrt{25} + \sqrt{16} ) + 2 \times \sqrt{36} = - (5 + 4) + 2 \times 6 = - 9 + 12 = 3[/tex]
e)
[tex] \sqrt{49} - \sqrt{64} + 2 \times (1 - \sqrt{9} ) = 7 - 8 + 2 \times (1 - 3) = - 1 + 2 \times ( - 2) = - 1 - 4 = - 5[/tex]
f)
[tex]2 \times \sqrt{100} \div \sqrt{16} + \sqrt{4} = 2 \times 10 \div 4 + 2 = 20 \div 4 + 2 = 5 + 2 = 7[/tex]
g)
[tex] \sqrt{64} \div ( \sqrt{16} - \sqrt{36} ) = 8 \div (4 - 6) = 8 \div ( - 2) = - 4[/tex]
Sper ca te-am putut ajuta!
