Which of the following is not true?
पर्याय
32 > 23
43 = 26
33 = 9
25 > 52
MCQ
उत्तर
33 = 9
Explanation:
- 32 > 23 = 3 × 3 > 2 × 2 × 2
9 > 8 (true) - 43 = 26 = (22)3 = 26
26 = 26 (true) ......[∵ (am)n = am×n] - 33 = 9
3 × 3 × 3 = 9
27 ≠ 9 (not true) - 25 > 52 = 2 × 2 × 2 × 2 × 2 > 5 × 5
32 > 25 (true)
Hence, 33 = 9 is not true.
