Question

simplifica con procedimiento por favor grasias a)8ab²/5ba-4ba²/25a² b)7(xy)²/17y³-14x²y⁴ /34y⁵ c)21xy-9xy+27yx²/9xy d)3x²/45x³+3x³/15x⁴

Answer 1

a) (8ab²/5ba)-(4ba²/25a²)
(1.6(-b)) - (0.16b)
(-1.6b) - (0.16b)
-1.6b - 0.16b
R=-1.76b

b) (7(xy)²/17y³) - (14x²y⁴ /34y⁵)
(7x²y²/17y³) - (14x²y⁴ /34y⁵)
(7/17*x²(-y)) - (14/34*x²(-y))
(-7/17 x²y) - (-14/34 x²y)
-7/17 x²y + 14/34 x²y
-7/17 x²y + 7/17 x²y
R=0

c)21xy-9xy+(27yx²)/9xy
12xy + (27yx²)/9xy
12xy + 3(-x)
12xy - 3x
R= (3x)(4y - 1)

d)(3x²/45x³) + (3x³/15x⁴)
(3/45*(-x)) + (0.2(-x))
(-3/45 x) + (-0.2 x)
-3x/45 - 0.2x
R= -12x/45

SALUDOS!!!
