(3/64*5 1/3-1/3):(-1/3)^3+(-1)^5*(3/64*5 /3-1/3):(-1/3)^3+(-1)^5=
=( 3/64*5 1/3-1/3):(-1/3)^3) (1+(-1)^5) + (-1)^5= -1
1) 3\64*5 1/3 = 3*16/ 64*3 = 1/4
2) 1/4-1/3=(3-4)/12= -1/12
3)-1/12 : (-1/3)^3 = -1/12 * (-9)=9/12=3/4
4) 1+(-1)^5=1-1=0
5) 3/4*0=0
6) 0+(-1)^5=-1
б) (12 3/4* 2 -27) : (-3/4) ^3=3 5/9
1)12 3/4*2 = 51*2/4 =51/2
2)51/2-27=(51-54)/2= -3/2
3)-3/2:(-3/4)^3 = -3/2 * (-64/27)=3*64/2*27 = 32/9=3 5/9
