Am nevoie urgent [16 la puterea a doua :8 la a doua +31 la 121 : 81 la 30+(5 la a doua) la a treia :25 la a doua]

Răspuns :

16² : 8² + 3¹²¹ : 81³⁰ + ( 5²)³ : 25² = 32

= ( 2⁴ )² : ( 2³) ²  + 3¹²¹ : ( 3⁴) ³⁰+ 5⁶ : ( 5² )²=

= 2⁸ : 2⁶ + 3¹²¹ : 3¹²⁰ + 5⁶ : 5⁴ =

= 2 ⁽ ⁸ ⁻ ⁶ ⁾  + 3 ⁽ ¹²¹ ⁻ ¹²⁰ ⁾ + 5⁽ ⁶ ⁻ ⁴ ⁾ =

= 2²  + 3¹ + 5² =

= 4 + 3 + 25 =

= 32
