# Lesson 7

Practice with Rational Bases

### Problem 1

Write with a single exponent:

- \(\frac{7^6}{7^2}\)
- \((11^4)^5\)
- \(4^2 \boldcdot 4^6\)
- \(6 \boldcdot 6^8\)
- \((12^2)^7\)
- \(\frac{3^{10}}{3}\)
- \((0.173)^9 \boldcdot (0.173)^2\)
- \(\frac{0.87^5}{0.87^3}\)
- \(\frac{(\frac{5}{2})^8}{(\frac{5}{2})^6}\)
