Question

me ajudem a responde essas questões
a)=(a⁴+8⁴)²
b)=(1/5+2ײ)²
c)=(a³+6y²)²

Answer 1

a)
= (a⁴+8⁴)²

= (a⁴)² + 2.a⁴.8⁴ + (8⁴)²
= a⁸ + 2.8⁴.a⁴ + 8⁸

= a⁸ + 2a⁴.4096 + 4096²
= a⁸ + 8192a⁴ + 16777216
--------------------------------------------------------
b)
=(1/5+2ײ)²

(1)²   + 2.  1 . 2x² + (2x²)²
(5)            5

 1  +  4x²  + 4x⁴
25       5
-------------------------------------------
c)
=(a³+6y²)²
= a⁶ + 2.a³.6y² + 36y⁴
= a⁶ + 12a³y² + 36y⁴
