Bot GPT-4 Turbo Let's simplify the given expression step by step:
−15 + 45(15e−10) − 10e
First, distribute the 45 into the parentheses:
−15 + (45 * 15e) − (45 * 10) − 10e
−15 + 675e − 450 − 10e
Next, combine like terms:
675e − 10e − 15 − 450
665e − 465
This simplifies the expression, but it doesn't match any of the given response options as they involve powers of 10. It seems like there might be a misunderstanding or a typo in the options. The operation here is algebraic simplification, not scientific notation, and "e" seems to stand for a variable (as commonly used in mathematics), not the base of the natural logarithm (approximately 2.718) or an exponent notation. Without further information, the given options do not apply to the simplified expression. If "e" is just a variable, the correct simplification would be:
665e − 465
This doesn't seem to correspond to any of the provided multiple-choice answers. If there was additional context or a specific interpretation of "e" intended in the problem, please provide that for an accurate evaluation.
