E)(5x²+1)²=(5x²)²+2.(5x²).1+1²==> 25x^4 + 10x² + 1
============================================
F)(11+pq)² = 11² + 2.11(pq) +(pq)²==> 121 + 22pq + p²q²
G)(x+0,5)² = x² + 2.x(0,5) +(0,5)²==> x² + x + 0,25
H)(x+½)² = x² + 2.x(1/2) +(1/2)²==> x² + x + 1/4 ou x² + x + 0,25
Como pode ver o resultado de F e G são iguais.
