Răspuns:

Explicație pas cu pas:

a)

=4/3-5/6*12/5

= 4/3- ³⁾2

=4/3-6/3

= - 2/3

-

b)

=2,89+5-4,2

= 7,89-4,2

=3,69

-

c)

=3-2/5*{ 3-2/5*[3-2/5*(⁶⁾1-1/6)]}

= 3-2/5*{ 3-2/5*[ 3-2/5*(6/6-1/6)]}

= 3-2/5*[ 3-2/5*(3-2/5*5/6)]

= 3-2/5*[ 3-2/5*(³⁾3-1/3)]

= 3-2/5*[3-2/5*(9/3-1/3)]

= 3-2/5*(3-2/5 *8/3)

= 3- 2/5*(¹⁵⁾3-16/15)

=3-2/5*(45/15-16/15)

= 3-2/5*29/15

= ⁷⁵⁾3-58/75

=225/75-58/75

=167/75

-

d)

=1- 9,75 +24-1

= - 8,75+24-1

= 15,25-1

= 14,25
