Răspuns:

Explicație pas cu pas:

$(\frac{1}{2})^{7} *(\frac{1}{2})^{3} :(\frac{1}{2})^{8} =\\(\frac{1}{2})^{7+3} :(\frac{1}{2})^{8} \\(\frac{1}{2})^{10} :(\frac{1}{2})^{8} \\(\frac{1}{2})^{10-8} \\(\frac{1}{2})^{2}$

$(-\frac{2}{3})^{24} *(-\frac{2}{3})^{11} : [(-\frac{2}{3})^{3}]^{11} \\=(-\frac{2}{3})^{24+11}:(-\frac{2}{3})^{3*11}\\=(-\frac{2}{3})^{35} : (-\frac{2}{3})^{33}\\=(-\frac{2}{3})^{35-33}\\\\=(-\frac{2}{3})^{2}=\frac{4}{9}$
