Answer 1

Resposta:

62 ou 46

Explicação passo a passo:

Se a expressão for 16(16-17)² +9(17-17)²+4(18-17)²+ 2(19-17)²+1(20-17)²+1(22-17)²​

$16*(16-17)^{2}-9*(17-17)^{2}+4*(18-17)^{2}+2*(19-17)^{2}+1*(20-17)^{2}+1*(22-17)^{2}\\\\=16*(1)^{2}-9*(0)^{2}+4*(1)^{2}+2*(2)^{2}+1*(3)^{2}+1*(5)^{2}\\\\=16*1-9*0+4*1+2*4+1*9+1*25\\\\=16-0+4+8+9+25\\\\=16+4+8+9+25\\\\=62$

Se a expressão for 16(16-17)² +9(17-17)²+4(18-17)²- 2(19-17)²+1(20-17)²+1(22-17)²

$16*(16-17)^{2}-9*(17-17)^{2}+4*(18-17)^{2}-2*(19-17)^{2}+1*(20-17)^{2}+1*(22-17)^{2}\\\\=16*(1)^{2}-9*(0)^{2}+4*(1)^{2}-2*(2)^{2}+1*(3)^{2}+1*(5)^{2}\\\\=16*1-9*0+4*1-2*4+1*9+1*25\\\\=16-0+4-8+9+25\\\\=16+4-8+9+25\\\\=46$
