Odpowiedź:
a) = 7- (-4) = 7+4=11
b) = 4 * 1/5 + 6/2 = 4/5 + 3 = 3 całe i 4/5
c)
[tex] \sqrt[3]{81 \times \sqrt{81} } = \sqrt[3]{81 \times 9} = 9[/tex]
d) =
[tex] \sqrt{4 \sqrt{4 \sqrt{16} } } = \sqrt{4 \sqrt{4 \times 4} } = \sqrt{4 \times 4} = 4[/tex]
e) = 5-4+ √9 = 1+3= 4
f) = 30 : 5 + 6 = 6+6= 12
