Zadanie 2
[tex](-8) + 24 - 6 = 24 - 14 = 10\\(-\frac{3}{4} ) * \frac{8}{12} = - \frac{2}{4} = - \frac{1}{2} = -0,5\\1\frac{2}{3} : \frac{3}{5} = \frac{5}{3} : \frac{3}{5} = \frac{5}{3} * \frac{5}{3} = \frac{25}{9} = 2 \frac{7}{9} \\(0,5)^{2} = 0,5 * 0,5 = 0,25\\(3 \frac{1}{2})^{2} =(3,5)^{2} = 3,5 * 3,5 = 12,25[/tex]
Zadanie 3:
[tex]3^{2} * 3 * 3^{5} = 3^{2} * 3^{1} * 3^{5}= 3^{8} \\7^{4} : 7^{2} * 7^{1} = 7^{3} \\3^{4} * 4^{4} = (3*4)^{4} = 12^{4} \\16^{5} : 8^{5} = (2^{4}) ^{5} : (2^{3}) ^{5} = 2^{20} : 2^{15} = 2^{5} \\(4^{3}) ^{5} = 4^{15}[/tex]
