Question

9. Which of the following inequalities is true for all real values of x? A. 2 > 0 > 0 B. 1 C. > 0 x 2+1 D. >O x² +1

Answer 1

Let's start calculating the value of √(27):

√(27) = √(9*3) = √(9)*√(3) = 3√(3) ≈ 5.196152423

So:

5.196152423 > 5.0

and

5.196152423 < 5.2

Therefore:

5.0 < √(27) < 5.2
