Question

(4+8+12+16+....+4000):(2+4+6+8+....+2000)+(2011+37):2 la 10

Answer 1

Răspuns: 4

Explicație pas cu pas:

S= 4+8+12+16+...+4000

S=4000+3996+3992+3988+...+4

2S=4004+4004+4004+...+4004  de 1000 ori

2S=4004*1000

2S=4 004 000

S=2 002 000

T=2+4+6+8+...+2000

T=2000+1998+1996+1994+...+2

2T=2002+2002+2002+2002+...+2002 de 1000 ori

2T=2002*1000

2T=2 002 000

T=1 001 000

S:T+2048:2¹⁰

2+2¹¹:2¹⁰

2+2=4
