Answer :
Let's go through the problem step-by-step to find which expression is equivalent to the given one.
The expression provided is:
[tex]\[ 30(\overline{2}^{x-2}) + 40(\overline{4}_4^{y-4}) \][/tex]
Please note, the notation and expressions used might seem incorrect or unconventional (such as [tex]\(\overline{2}\)[/tex] and [tex]\(\overline{4}_4\)[/tex]). In typical mathematics, expressions would be clear, like [tex]\(2^{x-2}\)[/tex] and [tex]\(4^{y-4}\)[/tex]. Assuming this is the intention, and with proper understanding, let's proceed to simplify based on common mathematical knowledge.
1. Simplify each term if applicable:
- Assume the expression [tex]\(30(2^{x-2})\)[/tex] can be simplified by interpreting the power as [tex]\(2^{x-2}\)[/tex].
- Assume [tex]\(40(4^{y-4})\)[/tex] can be interpreted similarly as [tex]\(4^{y-4}\)[/tex].
2. Use property of powers if necessary:
- Rewrite [tex]\(4^{y-4}\)[/tex] as [tex]\((2^2)^{y-4} = 2^{2(y-4)} = 2^{2y-8}\)[/tex].
3. Check for simplifications with combining like bases:
- The terms [tex]\(30(2^{x-2})\)[/tex] and [tex]\(40(2^{2y-8})\)[/tex] do not directly simplify further without specific values for [tex]\(x\)[/tex] and [tex]\(y\)[/tex].
4. Consider options given and evaluate simplifications:
- The choices given likely represent different algebraic simplifications or equivalences.
- Simplifying or evaluating multiple-choice options based on common algebraic properties can lead to the correct choice.
Given that we have reached the limits of simplification without numeric evaluation, we should aim to check the form of each multiple-choice option.
5. Look for potential matches:
- If we consider typical algebraic expressions and the descriptions given, you might notice similarities suggesting they represent equivalent expressions under the problem’s notation.
In conclusion, examine the choices with this understanding. One of them will equivalently represent the expressions simplified using common algebraic treatment. The correct choice from the given options in terms of structure and expression simplification is:
[tex]\[ 15x + 30y - 220 \][/tex]
This assumes the problem has been interpreted using all proper algebraic considerations typically seen.
