Show answers and working
1. 81 and 9
9² = 9 × 9 = 81 √81 = 9 because 9 × 9 = 81
2. 64 and 8
8² = 8 × 8 = 64 √64 = 8 because 8 × 8 = 64
3. 144 and 12
12² = 12 × 12 = 144 √144 = 12 because 12 × 12 = 144
4. 9 and 3
3² = 3 × 3 = 9 √9 = 3 because 3 × 3 = 9
5. 8
Multiply 2 by itself 3 times. 2 × 2 × 2 = 8
6. 16
Multiply 2 by itself 4 times. 2 × 2 × 2 × 2 = 16
7. 27
Multiply 3 by itself 3 times. 3 × 3 × 3 = 27
8. 64
Multiply 4 by itself 3 times. 4 × 4 × 4 = 64
9. x^2
Multiplying: add the powers → x^4. Dividing: subtract the powers → x^4 ÷ x^2 = x^2.
10. x^9
Multiplying: add the powers → x^11. Dividing: subtract the powers → x^11 ÷ x^2 = x^9.
11. x^9
Multiplying: add the powers → x^12. Dividing: subtract the powers → x^12 ÷ x^3 = x^9.
12. x^3
Multiplying: add the powers → x^6. Dividing: subtract the powers → x^6 ÷ x^3 = x^3.
Worked examples
Work out 10² and √100.
- 10² = 10 × 10 = 100
- √100 = 10 because 10 × 10 = 100
- Answer: 100 and 10
Evaluate 5^3.
- Multiply 5 by itself 3 times.
- 5 × 5 × 5 = 125
- Answer: 125
Simplify x^3 × x^5 ÷ x^6.
- Multiplying: add the powers → x^8.
- Dividing: subtract the powers → x^8 ÷ x^6 = x^2.
- Answer: x^2

Common mistakes
What learners typically get wrong, and how to fix it.
Works out 3² as 6.
Correction: 3² means 3 × 3, not 3 × 2.
Multiplies indices when multiplying powers.
Correction: x³ × x⁴ = x⁷ — add, don't multiply.
Teacher tips
- · Write powers out in full before using index laws.
Parent tips
- · Spot square numbers on tiles or a chessboard.
Real-life applications
- · Area in square units, computer storage (powers of 2).
