34. Each person silently remembers two numbers that are not equal to 0. Calculate the square of the sum of these two numbers, and record the result as “共”. Calculate the square of the difference of these two numbers, and record the result as “迎”. Then calculate the product of these two numbers, and record it as “接”. Using your “共”, “迎”, “接”, compute the expression:
$\left(\frac{\text { 共-迎 }}{\text { 接 }}\right)^{2}=$ ? . Please everyone answer together out loud.

Note: The Chinese characters “共”, “迎”, and “接” should be replaced with their English equivalents in the final answer. Here is the corrected version:

34. Each person silently remembers two numbers that are not equal to 0. Calculate the square of the sum of these two numbers, and record the result as “Sum”. Calculate the square of the difference of these two numbers, and record the result as “Diff”. Then calculate the product of these two numbers, and record it as “Prod”. Using your “Sum”, “Diff”, “Prod”, compute the expression:
$\left(\frac{\text { Sum-Diff }}{\text { Prod }}\right)^{2}=$ ? . Please everyone answer together out loud.

【Analysis】 $(a+b)^{2}=a^{2}+2 a b+b^{2},(a-b)^{2}=a^{2}-2 a b+b^{2}$. First, you need to understand these two expansions before performing the calculation.
【Solution】Solution: Let these two numbers be $a, b$.
$$
\begin{array}{l}
\text { 共 }=(a+b)^{2}, \text { 迎 }=(a-b)^{2}, \text { 接 }=a b \\
\frac{\text { 共-迎 }}{\text { 接 }}=\frac{(a+b)^{2}-(a-b)^{2}}{a b} \\
=\frac{a^{2}+2 a b+b^{2}-a^{2}+2 a b-b^{2}}{a b} \\
=\frac{4 a b}{a b} \\
=4
\end{array}
$$

Original expression $=\left(\frac{\text { 共-迎 }}{\text { 接 }}\right)^{2}=4^{2}=16$
Answer: It is 16
