Q1. 6 × 6 = ? (Square of 6)Solution: 36
Multiply 6 by itself 2 times: 6 × 6 = 36. So, it’s 36.
Q2. 3 × 3 × 3 = ? (Cube of 3)
Solution: 27
Multiply 3 by itself 3 times: 3 × 3 = 9, then 9 × 3 = 27. So, it’s 27.
Q3. 4 × 4 × 4 = ? (Cube of 4)
Solution: 64
Multiply 4 by itself 3 times: 4 × 4 = 16, then 16 × 4 = 64. So, it’s 64.
Q4. 11 × 11 = ? (Square of 11)
Solution: 121
Explanation: Multiply 11 by itself 2 times: 11 × 11 . So, it’s 121.
Q5. What number times itself is 25? (Square root of 25)
Solution: 5
Explanation: Pair 25 as 25. Last digit is 5, so it’s 5 (5 × 5 = 25).
Q6. What number times itself 3 times is 8? (Cube root of 8)
Solution: 2
Explanation: Try 2: 2 × 2 = 4, 4 × 2 = 8. It fits! So, it’s 2.
Q7. What number times itself is 64? (Square root of 64)
Solution: 8
Explanation: Pair 64 as 64. Last digit is 4, so it could be 2 (2 × 2 = 4) or 8 (8 × 8 = 64). Since it’s 64, it’s 8.
Q8. What number times itself 3 times is 27? (Cube root of 27)
Solution: 3
Explanation: Try 3: 3 × 3 = 9, 9 × 3 = 27. It fits! So, it’s 3.
Q9. You have 64 blocks in a cube shape. How many blocks on each side? (Cube root of 64)
Solution: 4
Explanation: Try 4: 4 × 4 = 16, 16 × 4 = 64. It fits! So, each side has 4 blocks.
