Question

Oblicz:
(1 1/6 - 5 3/4 ) x(-12,3 +3,3)do kwadratu =
(-0,3)do sześcinu : (-1 + 2/5) do kwadratu =
(-2/3)do kwadratu x (-12,3+3,3)do kwadratu=
(2,5- 2 1/3)do kwadratu -(-1/3)do sześcinu : 2/3=

Answer 1

(1 i 1/6 - 5 i 3/4) * ( - 12,3 + 3,3)^2=

= ( 1 i 2/12 - 5 i 9/12) * (-9)^2=

= - 4 i 7/12 * 81=

= - 55/12 * 81=  (skracam 12 z 81)

= - 55/4 * 27 =

= - 1485/4=

= - 371 i 1/4




(-0,3)^3 : (-1 + 2/5)^2=

= - 0,027 : ( - 3/5)^2=

= - 0,027 : 9/25=

= - 0,027 : 36/100=

= - 0,027 : 0,36=

= - 0,075


lub na ułamkach zwykłych

(-0,3)^3 : (-1 + 2/5)^2=

= - 0,027 : ( - 3/5)^2=

= - 0,027 : 9/25=

= - 27/1000 * 25/9  =  (skracam 27 z 9 oraz 1000 z 25)

= - 3/40 * 1/1=

= - 3/40




(-2/3)^2 * (- 12,3 + 3,3)^2=

= 4/9 * (-9)^2=

= 4/9 * 81 = (skracam 9 z 81)

= 4/1 * 9=

= 36/1=

= 36



(2,5 - 2 i 1/3)^2 - (-1/3)^3 : 2/3=

= (2 i 5/10 - 2 i 1/3)^2 - (-1/27) * 3/2=

= (2 i 1/2 - 2 i 1/3)^2 + 1/27 * 3/2 = (skracam 27 z 3)

= ( 2 i 3/6 - 2 i 2/6)^2 + 1/9 * 1/2=

= (1/6)^2 + 1/18=

= 1/36 + 1/18=

= 1/36 + 2/36=

= 3/36 =

= 1/12
