Problem 1
Complete the table. Use powers of 64 in the top row and radicals or rational numbers in the bottom row.
| \(64^1\) | \(64^{\frac12}\) | \(64^0\) | \(64^{\text-1}\) | ||
| 64 | 4 | \(\frac18\) |
Problem 2
Suppose that a friend missed class and never learned what \(25^{\frac12}\) means.
- Use exponent rules to show the value of \(25^{\frac12} \boldcdot 25^{\frac12}\).
- Explain why this means that \(25^{\frac12}=5\).
Problem 3
Which expression is equivalent to \(16^{\frac12}\)?
