Question

Simplify the expression: a¹⁹ + x² - √9 - x?⁷⁹ + x² + 9 - x?

Answer 1

To simplify the given expression, combine like terms and simplify the square root.

Step-by-step explanation:

To simplify the expression a¹⁹ + x² - √9 - x?⁷⁹ + x² + 9 - x?, we can combine like terms and simplify the square root. Let's break it down step by step:

1. a¹⁹ + x² + √9 + x?⁷⁹ + x² + 9 - x
2. Combine like terms: 2x² + 19 - x - √9 - x?⁷⁹
3. Simplify the square root: 2x² + 19 - x - 3 - x?⁷⁹
4. Combining like terms again: 2x² - 2x - x?⁷⁹ + 16

So, the simplified expression is 2x² - 2x - x?⁷⁹ + 16.
