Discrimination is the act of making unjustified distinctions between human beings based on the groups, classes, or other categories to which they are perceived to belong.

Answer 2

Step-by-step explanation:

(-1/3)^-3= -3³

(2/3)^-4=(3/2)⁴

so,(x/y)

=>3³÷(3/2)⁴

=>3³×(2⁴/3⁴)

=>3^-1×2⁴

=>2⁴/3

so,

(a)

=>3/2⁴

(b)

=>(2⁴/3+3/2⁴)^-1

=>[(2⁴×2⁴+3×3)/2⁴×3]^-1

=>[(2^8+3²)/2⁴×3]^-1

=>(2⁴×3)/2^8+3²
