a) 4,5 * [ 5/9 + (-0,25) + (-1/24)

_________________________ =

4/7 : (- 1¾ )

b) (√⅖) ⁴ - ( 1,2 * 5/12 + 0,8/2³ ) : ( ½ - 1 ) =

PILNE . bardzo prosze o rozwiązanie.

Answer 1

a) 4,5 * [ 5/9 + (-0,25) + (-1/24)

_________________________     =

4/7 : (- 1¾ )

 

45/10*[5/9-25/100 - 1/24]

-------------------------------------  =

4/7 : (-7/4)

 

45/10*[1425/5400]

------------------------- =

4/7 * (-4/7)

 

57/48

-------  =

-16/49

 

= 57/48* (-49/16)=

=- 3 ⁴⁸⁹/₇₆₈

 

b) (√⅖) ⁴ - ( 1,2 * 5/12 + 0,8/2³ ) : ( ½ - 1 ) =4/25 - (1/2+1/10) : (-1/2)=

4/25-(6/10):(-1/2)=4/25+6/5=34/25
