Videos and lessons to help Grade 8 students know and apply the properties of integer exponents to generate equivalent numerical expressions.

For example, 3^{2} × 3^{–5} = 3^{–3} = 1/3^{3} = 1/27.

Common Core: 8.EE.1

- I can explain why a zero exponent produces a value of one.
- I can explain how a number raised to an exponent of -1 is the reciprocal of that

number. - I can explain the properties of integer exponents to generate equivalent numerical

expressions.

1. Multiplying Exponents of the same base

For example, 3^{2}x 3^{-5}= 1/3^{3}= 1/27

2. Dividing Exponents of the same base

For example, 3^{2}/ 3^{-1}= 1/3^{3}= 1/27

3. Expand an exponent by another exponent

For example (2^{2})^{3}= 64
