Final answer:

The correct expressions are: a) log₇ 10 = x and 7 = 10, c) log₁₀ 10 = x and 10¹⁰ = x. The other expressions are not equivalent.

Step-by-step explanation:

The correct expressions are:

  • a) log₇ 10 = x and 7 = 10
  • c) log₁₀ 10 = x and 10¹⁽ = x

In these expressions, we can see that the logarithm of 10 to base 7 or 10 is equal to x. This means that 7 raised to the power of x is equal to 10, or 10 raised to the power of x is equal to 10.

The other expressions are not equivalent because they do not satisfy the same relationship between the logarithm and the exponent.
