repede va rog

Answer 1

20•201•2010•a=2010-2000+20-10-2•10
8.080.200•a=2010-2000+20-10-20
8.080.200•a=10+20-10-20
8.080.200•a=0
a=0

Answer 2

Răspuns:

a=0

Explicație pas cu pas:

(20 ∙ 201 ∙ 2010) ∙ a = 2010 − 2000 + 20 − 10 − 2 ∙ 10

( 20 ∙ 201 ∙ 2010) ∙ a=10+20-10-20

( 20 ∙ 201 ∙ 2010) ∙ a=0/:( 20 ∙ 201 ∙ 2010)

a=0
