Grade 8 Exponents Worksheets w/ Answers Cheat Sheet
- Product Rule - When you multiply two exponents with the same base, simply add the exponents to combine them into one powerful exponent. It's like stacking identical building blocks - 23 × 24 becomes 27. Product Rule on Symbolab
- Quotient Rule - When dividing expressions with the same base, subtract the exponent in the denominator from the exponent in the numerator. Think of it as undoing part of the power - 57 ÷ 53 = 54. This rule turns big fractions into simple powers. Quotient Rule on Symbolab
- Power of a Power Rule - To raise a power to another power, multiply the exponents for extra turbo charge. It's like stacking power-ups in a video game - (32)4 = 38. Power of a Power on GreeneMath
- Power of a Product Rule - Distribute the exponent to each factor inside parentheses so everyone shares the power. For example, (2×3)4 becomes 24×34, splitting the work evenly. Power of a Product at ByteLearn
- Power of a Quotient Rule - Apply the exponent separately to both numerator and denominator. Picture spreading frosting equally on two cupcakes - (2/3)3 = 23/33. Power of a Quotient on Symbolab
- Zero Exponent Rule - Any non-zero base raised to the zero power equals one, because you've taken away all of its multiplying power. Remember, a0 = 1, so 70 = 1. Zero Exponent Lesson on GreeneMath
- Negative Exponent Rule - A negative exponent flips your base into the denominator as a positive power. It's like stepping downstairs instead of climbing - 2−3 = 1/23 = 1/8. Negative Exponents at ByteLearn
- Fractional Exponents - Fractional exponents link exponents to roots: the denominator tells you which root to take, the numerator how many times to raise. For example, 82/3 = (³√8)2 = 4. Fractional Exponents Guide
- Multiplying Different Bases with the Same Exponent - When different bases share an exponent, multiply the bases first then raise the result to that exponent. So 23×33 = 63. Multiplying Bases at Symbolab
- Dividing Different Bases with the Same Exponent - If different bases share the same exponent, divide the bases and then apply the exponent to the quotient. For instance, 42÷22 = 22 = 4. Dividing Bases at Symbolab
