Question

помогите нужно!!!!!!!!!!!!!!!!!!!!

Answer 1

=((1/6)4*1/2):(1/12)3=(1/1296*1/2)*1728/1=1728/(1296*2)=144/(108*2)=16:(12*2)=8:12=2/3. Ответ: 2/3.

Answer 2

$\frac{6^{-4}*2^{-1}}{ 12^{-3}} = ( \frac{1}{6^4}* \frac{1}{2} ):( \frac{1}{12^3} )=( \frac{1}{(2*3)^4*2} ): \frac{1}{(2^2*3)^3} =\\= \frac{1}{2^5*3^4}* \frac{2^6*3^3}{1} = \frac{2^6*3^3}{2^5*3^4}= \frac{2}{3}$
