Answer 2

Răspuns:

1)2^-4 = 1/2^4 = 1/16

5^-2 = 1/5^-2 = 1/25

6^-1 = 1/6

2)3^-3 = 1/3^3 = 1/27

2^-5 = 1/2^5 = 1/32

4^-2 = 1/4^2 = 1/16

3)(1/3)^-3 = 3^3 = 27

(5/2)^-1 = 2/5

(10/7)^-2 = (7/10)^2 = 49/100

4) (1/2)^-1 + (1/3)^-2 + (1/4)^-2 = 2+3^2 +4^2 = 2+9+16 = 27

5) (3/2)^-1 + (2/3)^-1 = 2/3+3/2 = 4+9/6 = 13/6

6) (1/5)^-1 + (2/3)^-2 + (1/6)^0 = 5 + (3/2)^2 + 1 = 5 + 9/4 +1 = 6 + 9/4 = 24+9 /4 = 33/4
