Question

Need some assistance with the following problem.

Answer 1

Answer:

The provided statement $\exists x(x^2-4=1)$ is true in the domain of real number.

Step-by-step explanation:

Consider the provided information.

Any equation or inequality with variables in it is a predicate in the domain of real numbers.

The provided statement is:

$\exists x(x^2-4=1)$

Here, we need to find the value of x for which the above statement is true.

Since the value of x can be any real number so we can select the value of x as √5

(√5)²-4=1

5-4=1

Which is true.

Thus, the provided statement $\exists x(x^2-4=1)$ is true.
