Răspuns:

Explicație pas cu pas:

a)

=10*(7/9+20/9)

= 10*27/9

=10*3

= 30

-

b)

=3/2*( 8/7-1/7)

= 3/2*7/7

=3/2/*1

= 3/2

-

c)

=4/3*(10/9-³⁾2/3)

= 4/3*(10/9-6/9)

= 4/3 *4/9

=16/27

-

d)

=7/12 *( 23/27+4/27)

= 7/12*27/27

= 7/12*1

= 7/12

-

e)

=2/34 *( 17/15+³⁾51/5)

=2/34*(17/15+153/15)

= 2/34⁽³⁴*170⁽³⁴/15

= 2*5/15

= 10⁽⁵/15⁽⁵

=2/3

-

f)

= 24/35*( ³⁾18/25+⁵⁾2/15+11/75)

= 24/35 * (54/75+10/75+11/75)

= 24/35*75/75

= 24/35*1

= 24/35

-

g)

=12/49*(⁷⁾81/25-⁵⁾1/35+⁷⁾4/25)

=12/49*( 567/175 -5/175 +28/175)

= 12/49*590⁽⁵/175⁽⁵

=12/49*118/35

=416/1715
