a) = 0
b) =
Explicație pas cu pas:
a)
4/12 = simplificam cu 4 = 1/3
8/24 = simplificam cu 8 = 1/3
3/9 simplificam cu 3 = 1/3
= [ (1/3)⁴ : (1/3)² - (1/3)⁵ : (1/3)³]³ x [(-12/11)²]⁵ =
= [ (1/3)⁴⁻² - (1/3)⁵⁻³]³ x (-12/11)¹⁰ =
= [(1/3)² - (1/3)²]³ x (-12/11)¹⁰ =
= 0 x (-12/11)¹⁰ =
= 0
b)
= [(-3/4)⁶⁻⁴ + (1/2)⁷⁻⁵]³ x (39/16) =
= [(-3/4)² + (1/2)²]³ x (39/16) =
= [9/16 + 1/4]³ x (39/16) =
= [(9+4/16)]³ x (39/16) =
= (13/16)³ x (3x13/16) =
= 3 x (13/16)⁴
