−15+45(15e−10)−10e

Let's solve the expression step by step:

The expression is:

\[ -15 + 45(15e^{-10}) - 10e \]

1. Calculate \( 45(15e^{-10}) \): \[ 45 \times 15 = 675 \quad \text{thus, } 45(15e^{-10}) = 675e^{-10} \]

2. Combine the terms: Substitute into the expression: \[ -15 + 675e^{-10} - 10e \]

3. Now, we simplify: The expression contains three terms: \( -15 \), \( 675e^{-10} \), and \( -10e \). This doesn't simplify further without specific numerical values for \( e \) or others.

Analyzing this whole expression, the variable terms won't be canceled or directly simplified without a specific context for their values.

Next, let's evaluate the coefficients in terms of decimal powers:

Since the terms involve \( e^{-10} \) and \( e \), we focus on their contributions as:

\(-15\) is a constant, \(675e^{-10}\) and \(-10e\) are variable dependent.

If we evaluate, in a manner looking for a specific output, it appears this expression doesn't yield one of the provided choices \( 2e^{-23} \), \( 2e^{+23} \), \( -2e^{-23} \), or \( -2e^{+23} \).

The provided options seem to stem from a transformation of this expression, possibly involving setting values related to \( e \) for a clearer resolution.

Since we can't reduce \( 675e^{-10} - 10e - 15 \) down to a specific multiple of 2 and express in terms of \( e^{-23} \) or others, the values may not correlate with typical factorial results without specific evaluations.

Let's assume a scenario that redefines the \( e\) values in terms of base scenarios:

By evaluating or transforming, one might reconvene on an approach which limits or allows factoring yielding constants based on shared terms.

Textextually, none of the given outcomes seems valid from the factorial expansions.

Therefore, the expression remains expressed as:

\[ -15 + 675e^{-10} - 10e \text{ (none of the given results)} \]

Final answer: None of the provided options accurately match the simplified expression.
