Answer 1

Zad 1
-64-64-(256-1024)=-128+768=640
zad 2
3*(7+8)-(1-(2+4)=45+5=50
zad 3
8/3-21/24+3/4=32/12-63/12+9/12=-32/12=-8/3=-2i2/3
zad 4
19/12+11/6-1/2*2/3=19/12+11/6-2/6=19/12+22/12-2/12=37/12=3i1/12

Answer 2

Zad1. (-4)³-4³-((1-5)⁴-5⁴)=4³(-1-1)-((5⁰-5¹)⁴-5⁴)=4³(-2)-(5(0-1)⁴-5⁴)=-(2²)³(2¹)-(5(-1)⁴-5⁴)=-(2⁶)(2¹)-(5⁴-5⁴)=-2⁷-0=-2⁷

zad2. 3×(7-(-2)³)-(1-(2-2²))=3*(7+2³)-(1-2(1-2))=3*7+3*2³-(1-2(-1)=
3*7+3*2³-(1+2)=3*7+3*2³-3=3(7+2³-1)=3(6+8)=3*14=42

zad3. 2⅔-5¼+0,75²=8/3-21/4+(3/4)²=32/12-63/12+9/16=-31/12
+9/16=-124/48+27/48=-97/48=-2 1/48

zad4. 1⁷/₁₂+1⅚-½×⅔=19/12+11/6-2/6=19/12+22/12-4/12=37/12=3 1/12
