Negative Indices and Power of a Power
🎬 Video Tutorial
(0:10) Negative Indices Rule: A negative index means taking the reciprocal of the base with a positive index. For example: $2^{-3} = \frac{1}{2^3} = \frac{1}{8}$(1:03) Applying Negative Indices on Fractions: Flip the fraction and use the positive index. For example: $\left(\frac{2}{3}\right)^{-2} = \left(\frac{3}{2}\right)^2 = \frac{9}{4}$(1:34) Power of a Power Rule: When raising a power to another power, multiply the indices. For example: $(2^3)^5 = 2^{3 \times 5} = 2^{15}$
