Question

Please help!! (please don’t reply if you’re just going to say “ don’t know “ etc please and thank you)

Answer 1

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

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
