Show answers and working
1. 16 and 4
4² = 4 × 4 = 16 √16 = 4 because 4 × 4 = 16
2. 36 and 6
6² = 6 × 6 = 36 √36 = 6 because 6 × 6 = 36
3. 4 and 2
2² = 2 × 2 = 4 √4 = 2 because 2 × 2 = 4
4. 49 and 7
7² = 7 × 7 = 49 √49 = 7 because 7 × 7 = 49
5. 625
Multiply 5 by itself 4 times. 5 × 5 × 5 × 5 = 625
6. 27
Multiply 3 by itself 3 times. 3 × 3 × 3 = 27
7. 8
Multiply 2 by itself 3 times. 2 × 2 × 2 = 8
8. 125
Multiply 5 by itself 3 times. 5 × 5 × 5 = 125
9. x^5
Multiplying: add the powers → x^10. Dividing: subtract the powers → x^10 ÷ x^5 = x^5.
10. x^6
Multiplying: add the powers → x^9. Dividing: subtract the powers → x^9 ÷ x^3 = x^6.
11. x^5
Multiplying: add the powers → x^8. Dividing: subtract the powers → x^8 ÷ x^3 = x^5.
12. x^3
Multiplying: add the powers → x^9. Dividing: subtract the powers → x^9 ÷ x^6 = x^3.
Worked examples
Work out 9² and √81.
- 9² = 9 × 9 = 81
- √81 = 9 because 9 × 9 = 81
- Answer: 81 and 9
Evaluate 4^4.
- Multiply 4 by itself 4 times.
- 4 × 4 × 4 × 4 = 256
- Answer: 256
Simplify x^4 × x^2 ÷ x^4.
- Multiplying: add the powers → x^6.
- Dividing: subtract the powers → x^6 ÷ x^4 = 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).
