Bonjour, je ne n’arrive pas cette exercices, pouvez vous m’aider ?

Bonjour

A = (50 +1)(50-1)

= 50^2 -1^2

= 2500 -1

= 2499

B = (100+7)(100-7)

B = 100^2 -7^2

B = 10 000 -49

B = 9 951

C = (500-2)(500+2)

C = 500^2 -2 2

C =  250 000 -4

C = 249 996

Je te laisse faire le dernier

Bonsoir

A = (50 + 1)(50 - 1)

A = 50^2 - 1^2

A = 2500 - 1

A = 2499

B = (100 + 7)(100 - 7)

B = 100^2 - 7^2

B = 10000 - 49

B = 9951

C = (500 - 2)(500 + 2)

C = 500^2 - 2^2

C = 250000 - 4

C = 249996

D = (1000 + 7)(1000 - 7)

D = 1000^2 - 7^2

D = 1000000 - 49

D = 999951
