Question

Calcule o valor da expressão

Answer 1

Resposta:

B = 21,1511111111

Explicação passo-a-passo:

B = (1/1)²+(1/2)-²+(1/3)²+(1/4)-²+(1/5)²

B = (1²/1²)+(1-²/2-²)+(1²/3²)+(1-²/4-²)+(1²/5²)

B = 1/1+1/0,25+1/9+1/0.0625+1/25

B = 1+4+0,111111111+16+0,04

B = 5+16,111111111+0,04

B = 21,111111111+0,04

B = 21,1511111111
