The distributive property: a(b + c) = ab + ac

-------------------------------------------------------------------

Factors of 56: 1, 2, 4, 7, 8, 14, 28, 56

Factors of  64: 1, 2, 4, 8, 16, 32, 64

GCF(56, 64) = 8

56 = 8 · 7

64 = 8 · 8

56 + 64 = 8 · 7 + 8 · 8 = = 8(7 + 8)

--------------------------------------------------------------------

Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30

Factors of 54: 1, 2, 3, 6, 9, 18, 27, 54

GCF(30, 54) = 6

30 = 6 · 5

54 = 6 · 9

30 + 54 =  6 · 5 + 6 · 9 = 6(5 + 9)

Answer:

a = -1 , b = 4 , c = 3 , d = 1

Step-by-step explanation:

The general rules of exponent:

1) \ a^m * a^n = a^{m+n}\\2) \ a^m / a^n = a^{m-n}\\3) (-1)^m = 1 \ (if \ m \ is \ +) and \ = \ -1 \ (if \ m \ is \ -)

===================================================

Given:

(-xy)^3 (xz) =ax^by^cz^d

The right hand side = (-xy)³ (xz) = (-1)³ x³ y³ x z = (-1) x⁴ y³ z

Comparing the right hand side with the left hand side

∴ a = -1

∴ b = 4

∴ c = 3

∴ d = 1
