Ответ: 1. а. 1/3^4 = 1/81 б. 1/4^2= 1/16 в. 4/3 г. -10^-3 = -1/10^-3= -0,001
д. 1.
2. а. х^-4 х Х = 4х х х ^1 = х ^ 4+1 = х^5
б. х^2 : х^ -1 = x^2+1=x^3
в. x^4 x X ^-3 / x^-2 = x/ x^-2 = x^3
3. ( х-1/x) ^2 x ( x^-2-2x^-1+1) = ( x/ x-1 ) ^2 x ( 1/x^2 - 2 x 1/x +1)= x^2/(x-1) ^2 x 1-2x+x^2/ x^2= x/(x-1) ^2 x (-(x-1))^2= 1/ (x-1)^2 x ( x-1)^2= 1
