Answer 1

Resposta:
Explicação passo-a-passo:
1) Calcule os quocientes:
a) (15x⁶) : (3x²) = 5x^4
R.: 5x^4
__________________
b) (16x⁴) : (8x) = 2x^3
R.: 2x^3
____________________
c) (-30x⁵) : (+3x³) = -10x^2
R.: - 10x^2
__________
d) (+8x⁶) : (-2x⁴) =
-8/2= -4
X^6/x^4= x^2
R.: - 4x^2
______________
e) (-10y⁵) : (-2y) =
(-10)/(-2)= 5
y⁵ : y = y^4
R.: 5y^4
____________
f) (-35x⁷) : ( +5x³) = -7x^4
R.: -7x^4
________
g) (+15x⁸) : (-3x²) = -5x^6
R.: -5x^6
_____________
h) (-8x) : (-8x) = 1
R.: 1
__________
i) (-14x³) : (+2x²) =
-14/2= - 7
X^3/x^2 = x
R : -7x
__________
j) (-10x³y) : (+5x²) =
= - 10/5= -2
= X^3.y / x^2 = x.y
R.: -2xy
_______________
k) (+6x²y) : (-2xy) =
R.: = -3x
________________
l) (-7abc) : (-ab) =
= 7
= abc/ab = c
R.: 7c
______________
m) (15x⁷) : ( 6x⁵) =
15/6:(3)/(3)= 5/2
X^7 / x^5 = x^2
R.: 5x^2/2
