Question

Am nevoie de ajutor,va rog!

Answer 1

Răspuns:

Explicație pas cu pas:

-√9 = -3

√8 = 2√2

(-3)^3 = -27

(0,1)^-1 = (1/10)^-1 = 10^1 = 10

√1 9/16 = √25/16 = 5/4

15/5 = 3

a)

{(0.1)^-1; 15/5}

b)

{-√9; (-3)^3; (0,1)^-1; 15/5}

c)

{2,1; -√9; (-3)^3; (0,1)^-1; √1 9/16; 15/5}

d)

{√8}

_________

M ∩ N = {(0.1)^-1; 15/5}

M ∩ Z = {-√9; (-3)^3; (0,1)^-1; 15/5}

M ∩ Q = {2,1; -√9; (-3)^3; (0,1)^-1; √1 9/16; 15/5}

M ∩ R = {2,1; -√9; √8; (-3)^3; (0,1)^-1; √1 9/16; 15/5}
