Question

1)9x-27x^4 2)18y^5+12y^4 3)56a^10 b^6-32a^4 b^8 4)36mn^5+63m^2 n^6

Answer 1

9x(1-3x^3)
6y^4(3y+2)
8a^4b^6(7a^6-4n^2)
9mn^5(4+7mn)

Answer 2

To simplify each expression, we can combine like terms:

1. 9x - 27x^4

Answer: -27x^4 + 9x

2. 18y^5 + 12y^4

Answer: 18y^5 + 12y^4

3. 56a^10 b^6 - 32a^4 b^8

Answer: 56a^10 b^6 - 32a^4 b^8

4. 36mn^5 + 63m^2 n^6

Answer: 63m^2 n^6 + 36mn^5

Remember to combine like terms by adding or subtracting coefficients of the same variables and exponents.
