Answer 1

Ответ:

Объяснение:

$\displaystyle\\\left(-1\frac{1}{3}\right)^2-\left(\frac{1}{2} \right)^3+\left(\frac{3}{16} \right)^0+(-1)^7=\\\\\\=\frac{16}{9} -\frac{1}{8}+1-1=\frac{16\cdot8-9}{72}=\frac{128-9}{72} =\frac{119}{72}=1\frac{47}{72}$

Answer 2

Объяснение:

$( - 1 \frac{1}{3} ) {}^{2} - ( \frac{1}{2} ) {}^{3} + ( \frac{3}{16} ) {}^{0} + ( - 1) {}^{7} =\left(-\frac{3+1}{3}\right)^{2}-\left(\frac{1}{2}\right)^{3}+\left(\frac{3}{16}\right)^{0}+\left(-1\right)^{7} =\left(-\frac{4}{3}\right)^{2}-\left(\frac{1}{2}\right)^{3}+\left(\frac{3}{16}\right)^{0}+\left(-1\right)^{7} =\frac{16}{9}-\left(\frac{1}{2}\right)^{3}+\left(\frac{3}{16}\right)^{0}+\left(-1\right)^{7} =\frac{16}{9}-\frac{1}{8}+\left(\frac{3}{16}\right)^{0}+\left(-1\right)^{7} =\frac{119}{72}+\left(\frac{3}{16}\right)^{0}+\left(-1\right)^{7} =\frac{119}{72}+1+\left(-1\right)^{7} =\frac{191}{72}+\left(-1\right)^{7} =\frac{191}{72}-1 =\frac{119}{72} = 1\frac{47}{72}$
