GED Math Preparation

Introduction

• The goal is to help individuals pass GED Math to progress in life, inspired by stories of perseverance and success.

Understanding Power Rules

Rule Identification

• A: $44^1 = 44$ (True)
• B: $789^0 = 1$ (True)
• C: $rac{5^9}{5^4} ≠ 5^{13}$, but should be $5^5$ (False)
• D: $8^5 * 8^3 = 8^8$ (True)
• E: $(8^5 * 8^5) = (8 * 8)^5$ (True)*

Key Takeaways

• Any number raised to the power of 1 equals the number itself.
• Any number raised to the power of 0 equals 1.
• For multiplication with the same base, add exponents.
• For division with the same base, subtract exponents.

Solving Math Questions

• Addressing common mistakes and guiding through correct methods for GED and HiSET math questions.

Examples Solved

1. Multiplication and Powers: Demonstrated correct application of power rules.
2. Tax and Tip Calculation: Broken down into tax calculation, addition of tax to base, and calculation of tip on total.
