Question

me podrian ayudar con esto , si no sabes no respondas porfa

Answer 1

Explicación paso a paso:

5.

a α b = 5a - 7b

Hallar : (4 α 2) α (6 α 4)

(4 α 2) α (6 α 4)

(5(4) - 7(2)) α (5(6) - 7(4))

(20-14) α (30-28)

6 α 2

5(6) - 7(2) = 30 - 14 = 16

6.

S = √[2(8) - 3 + 3(4) + 1 - 1]

S = √[16 - 3 + 12]

S = √25

S = 5

7.

a = 5² - (6)(4) = 1

b = 7² - (9)(5) = 4

c = 3² - (1)(2) = 7

Hallar :

b² - ac = 4² - (1)(7) = 16 - 7 = 9

8.

[(4+6+24)/2 - 1]/(14+6)/5

[34/2 - 1]/(20/5)

(17-1)/(4)

16/4 = 4

9.

(8+7)/(8-7) + (10+9)/(10-9)

15/1 + 19/1

15 + 19 = 34
