Power Expansion WorksheetMath Practice Power Expansion Name: Date: Write each exponent in expanded form. Early Finishers: Solve/evaluate the expression under the Val column. Model How to expand & solve: \( 5^3 \) = \( 5 \cdot 5 \cdot 5 \) | Val: 125 01 \( 2^4 \) = Val: 09 \( 9^3 \) = Val: 02 \( 5^3 \) = Val: 10 \( 3^2 \) = Val: 03 \( 10^2 \) = Val: 11 \( 2^6 \) = Val: 04 \( 3^5 \) = Val: 12 \( 12^2 \) = Val: 05 \( 7^2 \) = Val: 13 \( 5^4 \) = Val: 06 \( 4^3 \) = Val: 14 \( 10^5 \) = Val: 07 \( 8^4 \) = Val: 15 \( 7^3 \) = Val: 08 \( 6^2 \) = Val: Math Tip Don't multiply the base by the exponent! \( 3^2 \) is \( 3 \cdot 3 \), not \( 3 \cdot 2 \).
Power Expansion Answer KeyTeacher Resource Power Expansion Answer Key Subject: Mathematics • Grade 6 Reference key for grading the Power Expansion Worksheet. Expanded forms and early-finisher values are shown in blue. Model How to expand & solve: \( 5^3 \) = \( 5 \cdot 5 \cdot 5 \) | Val: 125 01 \( 2^4 \) = 2 • 2 • 2 • 2 Val: 16 09 \( 9^3 \) = 9 • 9 • 9 Val: 729 02 \( 5^3 \) = 5 • 5 • 5 Val: 125 10 \( 3^2 \) = 3 • 3 Val: 9 03 \( 10^2 \) = 10 • 10 Val: 100 11 \( 2^6 \) = 2 • 2 • 2 • 2 • 2 • 2 Val: 64 04 \( 3^5 \) = 3 • 3 • 3 • 3 • 3 Val: 243 12 \( 12^2 \) = 12 • 12 Val: 144 05 \( 7^2 \) = 7 • 7 Val: 49 13 \( 5^4 \) = 5 • 5 • 5 • 5 Val: 625 06 \( 4^3 \) = 4 • 4 • 4 Val: 64 14 \( 10^5 \) = 10 • 10 • 10 • 10 • 10 Val: 100,000 07 \( 8^4 \) = 8 • 8 • 8 • 8 Val: 4096 15 \( 7^3 \) = 7 • 7 • 7 Val: 343 08 \( 6^2 \) = 6 • 6 Val: 36 Grading Tip Ensure the number of factors matches the exponent exactly. The "Val" column shows the evaluated values for early finishers.
