c) 0, 01+ 100 x 0, 2+ 0, 1 x ( 2, 4- 0, 4 : 0, 01

Va rog si rezolzarea!

Answer 1

a)10 [ 0, 78 +( 40, 6-7,5) : 0,1]=
=10 [ 0, 78 +33,1 : 0,1]=
=10 ( 0, 78 +3,31)=
=10×33,88=338,8

b) 100 x ( 345:3, 45 + 3, 45: 345+ 345: 345)=
 100 x ( 100 + 0,01+ 1)=100×101,01=10101


c) 0, 01+ 100 x 0, 2+ 0, 1 x ( 2, 4- 0, 4 : 0, 01)=
= 0, 01+ 20+ 0, 1 x ( 2, 4- 40)=.
= 0, 01+ 20+ 0, 1 x( -37,6)=
= 0, 01+ 20- 3,76=
=16,25
