Question

{3-2x[5-(-2)^3:4-5x3)]}x(-10)^2

^ inseamna la puterea

Answer 1

Răspuns:

=(3-2x(5+8:4-15))x100

=(3-2x(5+2-15)x100

=(3-2x(-8))x100

=(3+16)x100

=19x100

=1900

Explicație pas cu pas:

Answer 2

{ 3 - 2 × [ 5 - ( - 2 ) ^ 3 : 4 - 5 × 3 ] } × ( - 10 ) ^ 2

{ 3 - 2 × [ 5 - ( - 8 ) : 4 - 15 ] } × 100 =

{ 3 - 2 × [ 5 - ( - 2 ) - 15 ] } × 100 =

[ 3 - 2 × ( 7 - 15 ) ] × 100 =

[ 3 - 2 × ( - 8 ) ] × 100 =

[ 3 - ( - 16 ) ] × 100 =

19 × 100 = 1900
