To determine which pairs of expressions are equivalent, let's evaluate each pair step by step.

  1. Pair: (43)³ and 43 ⋅ 43

    • (43)³ = 43 × 43 × 43 = 43 ⋅ 43 ⋅ 43
    • These expressions are equivalent.
  2. Pair: (34)⁴ and 38 ⋅ 38

    • (34)⁴ = 34 × 34 × 34 × 34
    • 38 ⋅ 38 = 38²
    • These expressions are not equivalent.
  3. Pair: 64 ⋅ 34 and 188

    • 64 × 34 = 2176
    • 188 is simply 188
    • These expressions are not equivalent.
  4. Pair: 43 ⋅ 53 and 203

    • 43 × 53 = 2279
    • 203 is simply 203
    • These expressions are not equivalent.
  5. Pair: (43)³ and 43 ⋅ 43 ⋅ 43

    • (43)³ = 43 × 43 × 43 = 43 ⋅ 43 ⋅ 43
    • These expressions are equivalent.

From the analysis, the pairs of equivalent expressions are:

  • (43)³ and 43 ⋅ 43 ⋅ 43

Thus, the equivalent pairs are:

  • (43)³ and 43 ⋅ 43 ⋅ 43

The only equivalent pairs are the first and the last pairs.
