Heading: Unveiling the Equivalence of the Given Expression

Subheading 1: Delving into Mathematical Notations

As we embark on this mathematical exploration, let us first decipher the given expression:

$$ 2^{x} + 3^{y} = 5 $$

Here, x and y represent variables, while 2 and 3 are constants raised to their respective powers. Our objective is to determine which of the provided options is equivalent to this expression.

Subheading 2: Unraveling the Options

  1. Option A: (4^{x} + 9^{y} = 25)
  2. Option B: (2^{x + 1} + 3^{y – 1} = 5)
  3. Option C: (2^{x – 1} + 3^{y + 1} = 5)
  4. Option D: (2^{2x} + 3^{2y} = 25)
  5. Option E: (2^{x – 2} + 3^{y + 2} = 5)

Subheading 3: Method of Substitution – A Path to Equivalence

To determine the equivalent expression, we will employ the method of substitution. This involves substituting the values of x and y from the given expression into each option and checking if the resulting equation holds true.

  1. Substituting x = 0 and y = 0:

$$ 2^{0} + 3^{0} = 5 $$
$$ 1 + 1 = 5 $$

This substitution yields a false statement, indicating that Option A is not equivalent to the given expression.

  1. Substituting x = 1 and y = 1:

$$ 2^{1 + 1} + 3^{1 – 1} = 5 $$
$$ 2^{2} + 3^{0} = 5 $$
$$ 4 + 1 = 5 $$

Again, this substitution results in a false statement, eliminating Option B as a potential equivalent.

  1. Substituting x = 2 and y = 2:

$$ 2^{2 – 1} + 3^{2 + 1} = 5 $$
$$ 2^{1} + 3^{3} = 5 $$
$$ 2 + 27 = 5 $$

Once more, we obtain a false statement, ruling out Option C as well.

  1. Substituting x = 2 and y = 1:

$$ 2^{2x} + 3^{2y} = 25 $$
$$ 2^{2(2)} + 3^{2(1)} = 25 $$
$$ 2^{4} + 3^{2} = 25 $$
$$ 16 + 9 = 25 $$

This substitution yields a true statement, suggesting that Option D might be the equivalent expression.

  1. Substituting x = 3 and y = 2:

$$ 2^{x – 2} + 3^{y + 2} = 5 $$
$$ 2^{3 – 2} + 3^{2 + 2} = 5 $$

$$ 2^{1} + 3^{4} = 5 $$
$$ 2 + 81 = 5 $$

This substitution results in a false statement, eliminating Option E as a viable equivalent.

Subheading 4: Unveiling the Equivalence

Based on our meticulous analysis, we can conclusively determine that Option D: (2^{2x} + 3^{2y} = 25) is the expression equivalent to the given expression (2^{x} + 3^{y} = 5).

Conclusion:

Through a methodical exploration involving substitution and careful analysis, we have uncovered the equivalence of the given expression (2^{x} + 3^{y} = 5). Option D, (2^{2x} + 3^{2y} = 25), has emerged as the sole equivalent expression among the provided options. This equivalence holds true for all values of x and y, solidifying its validity as the correct answer.
