Question
Identify the following as rational or irrational numbers. Give the decimal representation of rational numbers:$-\sqrt{64}$
✓
Answer
We have,$-\sqrt{64}$
$=-8$
$=-\Big(\frac{8}{1}\Big)$
$=-\Big(\frac{8}{1}\Big)$ can be expressed in the form of $\frac{\text{a}}{\text{b}},$
so $-\sqrt{64}$ is a rational number. Its decimal representation is -8.0.
