Answers
GPT-4o mini
To simplify the expression \( 5 + 10x - 3 - (-2)^7 \), we will start by calculating \( (-2)^7 \).
\[
(-2)^7 = -128 \quad \text{(since the negative base raised to an odd exponent is negative)}
\]
Now, substituting \(-128\) into the expression:
\[
5 + 10x - 3 - (-128) = 5 + 10x - 3 + 128
\]
Now, combine the constant terms:
\[
5 - 3 + 128 = 2 + 128 = 130
\]
So, the expression simplifies to:
\[
10x + 130
\]
Thus, the final simplified expression is:
\[
\boxed{10x + 130}
\]
\[
(-2)^7 = -128 \quad \text{(since the negative base raised to an odd exponent is negative)}
\]
Now, substituting \(-128\) into the expression:
\[
5 + 10x - 3 - (-128) = 5 + 10x - 3 + 128
\]
Now, combine the constant terms:
\[
5 - 3 + 128 = 2 + 128 = 130
\]
So, the expression simplifies to:
\[
10x + 130
\]
Thus, the final simplified expression is:
\[
\boxed{10x + 130}
\]

It looks like you're asking about numeric values for the expression \( 10x + 130 \). However, without a specific value of \( x \), we can't give a numerical answer that matches the options you provided (A. 103, B. 83, C. 1875, D. 1255).
Here’s a breakdown on how to evaluate \( 10x + 130 \):
1. If you provide a specific value for \( x \), I can compute \( 10x + 130 \) and see if it matches any of the provided answers.
2. Alternatively, none of the options can be conclusively chosen without a specific \( x \).
If you want to proceed, please provide the value of \( x \).

Thank you for clarifying that the \( x \) represents multiplication.
Let's simplify the expression:
\[
5 + 10 \cdot 3 - (-2)^7
\]
First, calculate \( (-2)^7 \):
\[
(-2)^7 = -128
\]
Now substitute this back into the expression:
\[
5 + 10 \cdot 3 - (-128) = 5 + 30 + 128
\]
Now, combine these values:
\[
5 + 30 + 128 = 163
\]
Thus, the simplified value of the expression is \( 163 \).
Since this value is not among the options you provided (A. 103, B. 83, C. 1875, D. 1255), it seems there might be a miscommunication regarding the expression. Please confirm or provide the original expression again if needed!
