Question

oblicz 30% wyrażenia 1,5+(2/3-3,6x5/12)/(-1/3)2

to 2 na końcu to potęga o (-1/3)

Answer 1

1,5+(2/3-3,6x5/12)/(-1/3)2 =

= 1,5+(2/3-36/10x5/12)/(-1/9)=

= 1,5+(2/3-180/120)/(-1/9)=

=1,5+(352/120)/(-1/9) =

=1,5+3168/120=

= 1,5+26,4=

= 27,9

Answer 2

[tex]={ 0,3 [1,5 + (2/3 - 3/2 *5/12)/-2/3](do potęgi 2)}- 1/3 ={ 0,3 [1,5 + (2/3 - 3/2 *5/12)/-2/3](do potęgi 2)}- 1/3 ={0,3 [3/2 + -5/6/-2/3] ={ 0,3 [1,5 + (2/3 - 3/2 *5/12)/-2/3](do potęgi 2)}- 1/3 ={0,3[ 9-5/6* (-2/3)] (do potęgi 2)} - 1/3 ={0,3[ 4/6* 4/25] (do potęgi 2) } -1/3+
