Answer 1

Respuesta:

P1.-

a) 5x⁴ - 3x⁴ + (2/3)x⁴ = [(15/3) - (9/3) + (2/3)]x⁴ = (8/3)x⁴

b) 7x³y² - 3y²x³ + 8x³y² = (7 - 3 + 8)x³y² = 13x³y²

c) (3/4)x⁶ + (5/6)x⁶ - (2/3)x⁶ = [(9/12) + (10/12) - (8/12)]x⁶ = (11/12)x⁶

d) (4/5)x⁴y³z - (7/8)y³zx⁴ + (7/12)zx⁴y³ = [(96/120) - (105/120) + (70/120)]x⁴y³z = (61/120)x⁴y³z

e) -3x⁴ + 4x⁴ - (2/3)x⁴ = [(-9/3) + (12/3) - (2/3)]x⁴ = (1/3)x⁴

f) 5x³ - 4x³ - (1/5)x³ = [(25/5) - (20/5) - (1/5)]x³ = (4/5)x³

g) -8x⁹ + 4x⁹ - 7x⁹ = (-8 + 4 - 7)x⁹ = -11x⁹

Espero te ayude uwu.
