Ex 1.
a=10^5 b=10^2 c=10^3 d=10^13 e=10^8 f=10^28 g=10^0
Ex 2.
1) cos EAF = AE/AF = 2/4 = 0,5 => inverse cos 0,5 = 60°
2) sin CAB = BC/AC => AC = BC/sin CAB
AC=6/sin(40)=9,33 environ
3) sin KAI = IK/IA => IA = IK / sin KAI
IA = 13 / sin(25) = 30,76 environ
Ex 3.
a=2^1=2
b=(-1,5)^5
c=(-5)^-12
d=18^4
Ex 4.
A=2²+5x4=4+20=24
B=(3x5²+2)x4^3=(3x25+2)x64=(75+2)x64=77x64=4928
C=(2^-2/3+7)+(10^3)^-1=0,25/10 + 1000^-1=0,025 + 0,001=0,026
