If 2 * 3 = 8, 3 * 4 = 81, then 4 * 5 = ?

This question was previously asked in
SSC CGL 2025 Tier 2 Paper 1 Question Paper (19-Jan-2026)
The correct answer is
1024

Pattern Recognition: 2 * 3 = 8

The question presents a pattern-based calculation rather than standard multiplication.

  • First case: 2 * 3 = 8. This can be represented as $2^3 = 8$.
  • Second case: 3 * 4 = 81. This can be represented as $3^4 = 81$.

The established pattern is that $a * b$ is calculated as $a^b$.

Applying the Pattern: 4 * 5

To find the result for 4 * 5, we apply the identified pattern $a^b$:

  1. Substitute $a=4$ and $b=5$.
  2. Calculate $4^5$.
  3. $4^5 = 4 \times 4 \times 4 \times 4 \times 4 = 1024$.

Therefore, 4 * 5 = 1024 based on the established pattern.
