3/4+5/8=6/8+5/8=11/8(amplificam cu 2pe 3/4)
7/12+2/3=7/12+8/12=15/12(amplificam pe 2/3 cu 4)
5/6+1/24=20/24+1/24=21/24(amplificam pe 5/6 cu 4)
a)
[tex] \frac{3}{4} ^{(2} + \frac{5}{8} = \frac{6 + 5}{8} = \frac{11}{8} [/tex]
b)
[tex] \frac{7}{12} + \frac{2}{3} ^{(4} = \frac{7+ 8}{12} = \frac{15}{12} \\ \: mai \: simplificam \: = \frac{5}{4} [/tex]
c)
[tex] \frac{5}{6}^{(4} + \frac{1}{24} = \frac{20 + 1}{24} = \frac {21}{24} = \frac{7}{8}[/tex]
