How to simplify using index laws
WebThis formula tells us that when dividing powers with the same base, the index in the denominator is subtracted from the index in the numerator. This is the second index law and is known as the Index Law for Division. Example 8. Solution: Note: Simplify the numerical coefficients first, and then apply the index law. Key Terms WebStudents will use index laws to simplify and evaluate numerical index expressions involving integer indices. For example: (2 6 × 2 -3) 2 = (2 6+ -3) 2 = (2 6-3) 2 = (2 3) 2 = 2 3×2 = 2 6 = 64 Common misunderstandings: Students may treat the index as a multiplier. For example, incorrectly thinking 5 2 means 5 × 2
