Question

pfvvv me ajudem nessas duas pliiiiiis urgenteeee​

Answer 1

Resolução

01)   Alternativa C

2.2.2 / 5.5.5

8 / 125

0,064

02)

a = (1/3)^2 * ∛64 + √25/81

a = 1/9 * 4 + 5/9

a= 4/9 + 5/9

a = 9/9 = 1

b= √0,04 + 2/3 . (3/5)^2

b= 0,2 + 2/3 . 9/25

b= 0,2 + 18/75

b= 1/5 + 18/75

mmc(75,5) = 5.5.3 = 75

75, 5 | 3

25 , 5 | 5

5 , 1 | 5

1 , 1   5^2 . 3

(75/5) . 1 + (75/75) . 18 / 75

15 + 18 / 75

33 / 75

b = 0,44

a + b = ?

1 + 0,44 = 1,44
