Answer 1

a) 2^-2+ 3^-1 = (1/2)^2 +1/3 = 1/4 +1/3 = 3/12 + 4/12 = 7/12

b) 3^-1 + 3^-2 + 3^-3 = 1/3 + (1/3)^2 + (1/3)^3 =1/3 + 1/9/ + 1/27 = 9/27 + 3/27 + 1/27 =3/27

c)2 + 2^2 + 2^3 = 2+4+8 = 14

d) (1/3)^3 * 3^2 + (1/4)^3 / 1/8 = 1/27 * 9 + 1/64 *8 = 1/3 + 1/8 = 8/24 + 3/24 = 11/24

e) 5^2 + (-3)^4 - 32 + 10^2= 25+81-32+100 = 174

f)4^2 + 6^2 -8^2 * 2^4 = 16 + 36 - (2^3)^-2 * 2^4= 52 - 2^-6 * 2^4= 52 - 2^-2= 52-(1/2)^2=52-1/4 = 51 3/4

 

Licze na naj :)
