1) 5,48*10^6
2) 4^8/4^3*(4^3)^2 = 4^5*4^6 = 4^11 = 4194304
3) [n^(-5)/(3m)^(-3)]^(-2)*4n^8*m^3 = (9n^10/m^6)*4n^8*m^3 = 36n^18/m^3
4) A) 5,4*10^4 > 3,7*10^4
B) 8,5*10^(-10) < 8,5*10^(-8)
C) 1,5*10^6 > 1,5*10^(-6)
5) A) (1,5*10^2) * (6,5*10^(-7)) = (1,5*6,5)
* 10^(2-7) = 9,75*10^(-5)
B) (2,4*10^8) : (1,6*10^10) = (2,4:1,6) * 10^(8-10) = (3:2) * 10^(-2) = 1,5*10^(-2)
