Срешением 2: 2^-2= 8^-2*4^3= (5^-2)^-1= 10^8/10^-5*10^-4= 10^0/10^-3= 3^-6*(3^-2)^-4=

 8^-2*4^3=(2^3)^-2 * (2^2)^3 = 2^ -6 *2^6 =2^0 = 1
2:2^-2=2*2^2 = 2 *4 = 8
(5^-2)^-1= 5^2 = 25
10^8/10^-5*10^-4= 10^(8+5 -4) = 10^9 = 1000 000 000
10^0/10^-3= 10^( 0+3) = 10 ^3 = 1000
3^-6*(3^-2)^-4= 3^-6 *3^8 = 3^2 = 9
