Answer 1

1)  $a^{4} +40 a^{2} -11 a^{3}$;

2. 21 a^{6} - 16 b^{5} +15;  3. 100c³- c² - 99;
4. $52 - 17 k^{4} -53k$

Answer 2

1. To simplify the expression 1 + 22a² - 40a³ + 18a² + 29a³ + a⁴ + 2, we can combine like terms. Like terms have the same variable(s) raised to the same exponent(s). Let's group the terms with the same variables and exponents together:

22a² + 18a² = 40a² -40a³ + 29a³ = -11a³

Now, the expression becomes: 1 + 40a² - 11a³ + a⁴ + 2

2. To simplify the expression -7b⁵ - 13b⁶ + 15 - 9b⁵ + 34b⁶, we can combine like terms:

-7b⁵ - 9b⁵ = -16b⁵ -13b⁶ + 34b⁶ = 21b⁶

Now, the expression becomes: -16b⁵ + 21b⁶ + 15

3. To simplify the expression 41c² + 62c³ - 99 - 42c² + 38c³, we can combine like terms:

41c² - 42c² = -c² 62c³ + 38c³ = 100c³

Now, the expression becomes: -c² + 100c³ - 99

4. To simplify the expression -52k + k⁴ - 18k⁴ + 52 + k, we can combine like terms:

-52k + k = -51k k⁴ - 18k⁴ = -17k⁴

Now, the expression becomes: -17k⁴ - 51k + 52 + k
