Question

calcula √B-D si
B=2+4+6+8+...+80
D=1+1+1+1+...+1 (40 términos)​

Answer 1

Verified answer

Respuesta:

40

Explicación paso a paso:

B=2+4+6+8+...+80 => 2n = 80 => n = 40 => n(n+1) = 40(40+1)=40(41)=1640

D=1+1+1+1+...+1 (40 términos)​ = 40

[tex]\sqrt{B - D}[/tex] = [tex]\sqrt{1640 - 40}[/tex] = [tex]\sqrt{1600}[/tex] = 40
