5-2/3*3-2/3                                  15-2/3                   15(-2/3-2/3)

(--------------)-1.5=(------------------)-1.5=(----------------------------)-1.5=

152/3*2-16/3                152/3*2-16/3                2-16/3

       15-4/3                  15(4/3*3/2)                   152(15 в квадрате)

(--------------)-1.5=-------------------=-------------------=

       2-16/3                   2(16/3*3/2)                    28(2 в восьмой степени)

       225

=---------=0,88-надеюсь понятно?

       256

(4^(-1/8))^1.6*16^0.6=4^((-1/8)*(8/5))*4^(2*0.6)=4^(-1/5)*4^(1.2)=4^((-0.2)+1.2)=4^1=4

[12^0.5*3^0.5*7^(5/3)]/[7^(2/3)*8^(-1/6)*8^(1/2)]=[36^0.5*7^((5/3)-(2/3))]/[8^((-1/6)+(1/2)]=6*7/8(-1/4)=70.63
