Question

Помогите пожалуйста

Answer 1

Ответ:

1) (7+3)² = 10² = 10 • 10 = 100

2) (8-6)² = 2² = 2 • 2 = 4

3) 10²-2² = (10-2)² = 8² = 8 • 8 = 64

4) 17² - 10² = (17-10)² = 7² = 7 • 7 = 49

5) (35-6)² = 29² = 29 • 29 = 841

6) (8-4)² = 4² = 4 • 4 = 16

Answer 2

Объяснение:

(7+3)^2 = 10^2 =100

(7+3)^2= 7^2 +2*7*3+3^2= 49+42+9=100

2) (8-6)^2 = 2^2=4

(8-6)^2= 8^2 - 2*8*6 +6^2=64 -96 +36= 100-96=4

3) 10^2 -2^2= (10-2)(10+2)= 8*12=96

10^2 - 2^2=100-4=96

4) 17^2 -10^2= (17-10)(17+10)= 7*27=189

17^2 -10^2=289- 100= 189

5)(35 -6)^2= 35^2 - 2*35*6+6^2= 1225 - 420+36= 841

(35-6)^2= 29^2=841

6) (8-4)^2= 8^2 - 2*8*4+ 4^2= 64 - 64 +16=16

(8-4)^2=4^2=16
