If A= x: x . is an integer and .x^2-9=0 B= x: x is a natural number and 2 x 5 C = x : x is a prime number 4 Then (B-C) A is,

Options

  1. A-3,3,4
  2. B2,3,4
  3. C3,4,5
  4. D2,3,5

Correct answer

A. -3,3,4

Step-by-step solution

aligned & A= x: x is an integer and x^2-9=0 & x^2=9 x= 3= -3,3 aligned aligned & B = x : x is a natural number and 2 x 5 & = 2,3,4 & C = x : x is a prime number 4 & = 2,3 & ( B - C ) A = 4 -3,3 = -3,3,4 aligned
