Question

Помогите пожалуйста срочно

Answer 1

$2^{-3}-(-2)^{-6}= (\frac{1}{2}) ^{3}-( \frac{1}{-2} )^{6}= \frac{1}{8} - \frac{1}{64} = \frac{8-1}{64} = \frac{7}{64}$

$\frac{125^{-4}}{25^{-5}} = \frac{(5^3)^{-4}}{(5^2){-5}} = \frac{5^{3*(-4)}}{5^{2*(-5)}} = \frac{5^{-12}}{5^{-10}} =5^{-12-(-10)}=5^{-12+10}=5^{-2}= (\frac{1}{5} )^2=$

$=\frac{1}{25} * \frac{4}{4} = \frac{4}{100} =0,04$

Answer 2

1/2³-(-1/2⁶)=1/8-1/64=8/64-1/64=7/64
1/125⁴:1/25⁵=25⁵/125⁴=5¹⁰/5¹²=1/5²=1/25=0,04
