Answer 1

1. 81+18b+b^2
3. 9c^2-12c+4

Answer 2

To simplify the expression, let's expand each squared term:

1. (9+b)² = (9+b)(9+b) = 81 + 18b + b²
2. (-z-3)² = (-z-3)(-z-3) = z² + 6z + 9
3. (3c-2)² = (3c-2)(3c-2) = 9c² - 12c + 4
4. (6m-4n)² = (6m-4n)(6m-4n) = 36m² - 48mn + 16n²
5. (-6y-2z)² = (-6y-2z)(-6y-2z) = 36y² + 24yz + 4z²
6. (1/4m+3n)² = (1/4m+3n)(1/4m+3n) = 1/16m² + 3/2mn + 9n²
7. (y²-6)² = (y²-6)(y²-6) = y⁴ - 12y² + 36
8. (b²-5y)² = (b²-5y)(b²-5y) = b⁴ - 10b²y + 25y²
9. (m²-n³)² = (m²-n³)(m²-n³) = m⁴ - 2m²n³ + n⁶
10. (4x²-3c)² = (4x²-3c)(4x²-3c) = 16x⁴ - 24x²c + 9c²
11. (0.9x+1⅓y)² = (0.9x+1⅓y)(0.9x+1⅓y) = 0.81x² + 2.4xy + 1.78y²

Now, let's combine all the simplified expressions together:

(81 + 18b + b²) * (z² + 6z + 9) * (9c² - 12c + 4) * (36m² - 48mn + 16n²) * (36y² + 24yz + 4z²) * (1/16m² + 3/2mn + 9n²) * (y⁴ - 12y² + 36) * (b⁴ - 10b²y + 25y²) * (m⁴ - 2m²n³ + n⁶) * (16x⁴ - 24x²c + 9c²) * (0.81x² + 2.4xy + 1.78y²)

To simplify this expression further, you would need specific values for the variables (b, c, m, n, x, y, and z). Without specific values, the expression remains in its factored form.
