Answer 2

It looks like you have an expression with variables "a" and "b" raised to various exponents. To simplify this expression, let's break it down step by step:

1. 9a²⁰b¹⁶ - 1: This part of the expression can't be simplified further. It remains as it is.

2. 8a¹⁰a¹⁸: Here, you can combine the "a" terms with the same base by adding their exponents. So, 8a¹⁰a¹⁸ becomes 8a^(10+18), which simplifies to 8a²⁸.

3. 0.9a⁵b⁹(10a¹⁵b⁷ + 2a⁵b⁹): Distribute the 0.9a⁵b⁹ into the terms inside the parentheses:

   0.9a⁵b⁹ * 10a¹⁵b⁷ + 0.9a⁵b⁹ * 2a⁵b⁹

Now, simplify each term:

9a^(5+15)b^(9+7) + 1.8a^(5+5)b^(9+9)

9a²⁰b²⁶ + 1.8a¹⁰b¹⁸

Now, we have simplified the entire expression:

9a²⁰b¹⁶ - 8a²⁸ + 9a²⁰b²⁶ + 1.8a¹⁰b¹⁸

Answer 3

It seems like you want to simplify the expression:

9a^20b^16 - 18a^10b^18 - 0.9a^5b^9(10a^15b^7 + 2a^5b^9)

Let's break it down step by step:

1. Start with the first term: 9a^20b^16.

2. Move on to the second term: -18a^10b^18.

3. Now, focus on the third term: -0.9a^5b^9(10a^15b^7 + 2a^5b^9).

   First, distribute -0.9 into the expression inside the parentheses: -0.9 * 10a^15b^7 - 0.9 * 2a^5b^9

   Simplify each term: -9a^15b^7 - 1.8a^5b^9

4. Now, we can rewrite the entire expression with the simplified terms: 9a^20b^16 - 18a^10b^18 - 9a^15b^7 - 1.8a^5b^9

That's the simplified form of the expression.
