Question

Given universal set $=\{-6,-5\frac{3}{4},-\sqrt{4},-\frac{3}{5},-\frac{3}{8},0,\frac{4}{5},1,1\frac{2}{3},\sqrt{8},3.01,\pi ,8.47\}$

From the given set, find the set of integers.

• A. $\{-6,-\sqrt{4},0,1\}$
• B. $\{-6,-\sqrt{4},0,\pi \}$
• C. $\{-\sqrt{4},0,1\}$
• D. Cannot be determined
  

Answer 1

The correct option is A $\{-6,-\sqrt{4},0,1\}$

Set of integers is $\{-6,-2,0,1\}$

As $\sqrt{4}=2$ therefore $\sqrt{4}$ also becomes an integer.

other numbers of the given set are fractions hence not integers.

Therefore the number which are integers are only $-6,-2,0,1$
