Question

(³₈+2⁵₈÷√⁴⁹₁₆)×0,25 kreska ulamkowa i pod spodem 0,125-³₄×(-2¹₃)

Answer 1

(3/8 + 2 i 5/8 : √(49/16) ) * 0,25

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

0,125 - 3/4 * (-2 i 1/3)

 

 

(3/8 + 21/8 : 7/4) * 0,25

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

0,125 - 3/4 * (-7/3)

 

 

(3/8 + 21/8 * 4/7) * 0,25

--------------------------------  =

0,125 - (-7/4)

 

 

(3/8 + 3/2) *0,25

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

0,125 + 1 i 3/4

 

(3/8 + 12/8) * 0,25

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

0,125 + 1,75

 

 

15/8 * 1/4

-------------------  =

1,875

 

 

15/32 : 1,875 = 15/32 : 1 i 7/8 = 15/32 : 15/8 = 15/32 * 8/15 = 1/4

Answer 2

  (3/8 + 2 5/8 : √(49/16) * 0,25 :[0,125 - 3/4 *(-2 1/3) =

= (3/8 + 21/8 : 7/4)* 25/100 : [125/1000 - 3/4 *(-7/3)] =

= (3/8 + 21/8 * 4/7)*1/4 : [5/40 + 21/12] =

= (3/8 + 3/2)*1/4 : (45/360 + 630/360) =

= (3/8 + 12/8)*1/4 : 675/360 =

= 15/8 * 1/4 * 360/675 =

= 1/4
