Vă roggg dau 100de puncte+abonare+coroană!!​

Answer 1

Răspuns:

Explicație pas cu pas:

c)

[(3/5)⁴]⁶*(3/5)⁸:(3/5)²⁾⁵

= (3/5)⁴ˣ⁶*(3/5)⁸:(3/5)³²

= (3/5)²⁴⁺⁸ *(3/5)³²

= (3/5)³²:(3/5)³²

=(3/5)³²⁻³²

= (3/5)⁰

= 1

-

d)

=(5/11)³ˣ¹⁵*(5/11)²⁰:(5/11)⁶⁵

= (5/11)⁴⁵ * ( 5/11)²⁰ : (5/11)⁶⁵

= (5/11)⁴⁵⁺²⁰ : (5/11)⁶⁵

=(5/11)⁶⁵:( 5/11)⁶⁵

= (5/11)⁶⁵⁻⁶⁵

= (5/11)⁰

= 1
