Oblicz :

a ) -1 1/4 * ( -4 ) =

b ) -6 2/3 : 2 =

c ) -0,2 * ( -0,2 ) =

d ) -3 1/3 * ( -3 ) =

e ) ( -3 ) do potęgi 2 * 1/3 =

f ) ( 1/3) do potęgi 2 * ( -9) =

g ) -6 do potęgi 2 : 1/2 =

h ) 3 3/4 : ( -1,25) do potęgi 2 =

Answer 1

a  ) -1 1/4 * ( -4 ) = - 5/4 *(-4) = 5

 

b ) -6 2/3 : 2 = -20/3 * 1/2 = -20/6 = -3 2/6 = - 3 1/3

 

c ) -0,2 * ( -0,2 ) = 0,04

 

d ) -3 1/3 * ( -3 ) = -10/3 * (-3) = 10

 

e ) ( -3 )² * 1/3 = 9*1/3 = 3

 

f ) ( 1/3)²* ( -9) = 1/9 *(-9) = -1

 

g ) -6² : 1/2 = -36 *2 = -72

 

h ) 3 3/4 : ( -1,25)² = 15/4 : 1,5625 = 3,75:1,5625 = 2,4
