Question

zad.4

a)5/8;7/12

b)-4,27+3,2

c)-1 1/2+(-3 5/6)

d)1 9/16 w pierwiastku

e)(-3) do potęgi 3

Answer 1

5/8 * 12/7 = 15/14
-1,07
-3/2 -23/6 = - 9 / 6 - 23 / 6 = -32/6
25 /16 w pierwiastku =  5/4
-3 *(-3)*(-3) = - 27 
:)

Answer 2

a) 5/8 : 7/12 = 5/8 * 12/7 = 60/56 = 1 i 4/56 = 1 i 1/14

b) -4,27 + 3,2 =  - 1,07

c) -1½ + (-3 i 5/6) = -3/2 + (-23/6) = - 9/6 + (-23/6) = -32/6 = -5 i 2/6 = -5⅓

d) √1 i 9/16 = √25/16 = 5/4 = 1¼

e) (-3)³ = 27
