Answer 1

Răspuns:

b) =3+(2·11+2)/11·[(125/100⁽²⁵-3/9⁽³)]

=3+24/11·(³⁾5/4-⁴⁾1/3)]

=3+24/11·(15/12-4/12)

=3+24/11·11/12

=3+2=5

____________

c) [(1·3+1)/3+(16-1)/90]²·(15/10)⁽⁵-1/2

=[(4/3+(15/90)⁽¹⁵]²·3/2-1/2

=(⁴⁾4/3+²⁾1/6)²·3/2-1/2

=(16/12+2/12)²·3/2-1/2

=(18/12)²·3/2-1/2

=(3/2)²·3/2-1/2

=(3/2)²⁺¹-1/2

=(3/2)³-1/2

=27/8-⁴⁾1/2

=(27-4)/8=23/8=2,875
