Negative Exponents
Negative Exponents is a skill on Pengi from Lesson 51: Negative Exponents and Scientific Notation for Small Numbers in Saxon Math, Course 3.
Key Concepts
Property For any nonzero number $x$ and any integer $n$: $$x^{ n} = \frac{1}{x^n}$$.
Examples $2^{ 3} = \frac{1}{2^3} = \frac{1}{8}$ $10^{ 2} = \frac{1}{10^2} = 0.01$ $5a^{ 4} = \frac{5}{a^4}$.
Explanation A negative exponent is a secret 'flip' instruction! It doesn't make the number negative; it tells the base to move to the other side of the fraction bar. The exponent then loses its negative sign. It’s the ultimate switcheroo for simplifying expressions!
