Show answers and working
1. 36 and 6
6² = 6 × 6 = 36 √36 = 6 because 6 × 6 = 36
2. 81 and 9
9² = 9 × 9 = 81 √81 = 9 because 9 × 9 = 81
3. 144 and 12
12² = 12 × 12 = 144 √144 = 12 because 12 × 12 = 144
4. 121 and 11
11² = 11 × 11 = 121 √121 = 11 because 11 × 11 = 121
5. 64
Multiply 4 by itself 3 times. 4 × 4 × 4 = 64
6. 8
Multiply 2 by itself 3 times. 2 × 2 × 2 = 8
7. 625
Multiply 5 by itself 4 times. 5 × 5 × 5 × 5 = 625
8. 81
Multiply 3 by itself 4 times. 3 × 3 × 3 × 3 = 81
9. x^5
Multiplying: add the powers → x^11. Dividing: subtract the powers → x^11 ÷ x^6 = x^5.
10. x^1
Multiplying: add the powers → x^7. Dividing: subtract the powers → x^7 ÷ x^6 = x^1.
11. x^10
Multiplying: add the powers → x^12. Dividing: subtract the powers → x^12 ÷ x^2 = x^10.
12. x^9
Multiplying: add the powers → x^13. Dividing: subtract the powers → x^13 ÷ x^4 = x^9.
Worked examples
Work out 5² and √25.
- 5² = 5 × 5 = 25
- √25 = 5 because 5 × 5 = 25
- Answer: 25 and 5
Evaluate 4^4.
- Multiply 4 by itself 4 times.
- 4 × 4 × 4 × 4 = 256
- Answer: 256
Simplify x^2 × x^6 ÷ x^4.
- Multiplying: add the powers → x^8.
- Dividing: subtract the powers → x^8 ÷ x^4 = x^4.
- Answer: x^4

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).
