Which of these expressions is an indeterminate form?
Choose one option.
Show answer
- C. \(\frac{0}{0}\)
Explanation
\(\frac{0}{0}\) is indeterminate. \(\frac{5}{0}\) tends to infinity, while \(\frac{3}{4}\) and \(\frac{7}{1}\) are defined numbers.
Review the concept: Indeterminate forms
An indeterminate form is a limit expression, such as \(\frac{0}{0}\) or \(\frac{\infty}{\infty}\), whose value cannot be deduced from the limits of its parts.
\[\frac{0}{0},\ \frac{\infty}{\infty},\ 0\cdot\infty,\ \infty-\infty\]
