We are given that:
x3∗y2∗z=360
Now multiple cases are possible here:
Case 1:
When x=−2 and y=−3 and z=−5, then:
x3∗y2∗z=(−2)∗(−2)∗(−2)∗(−3)∗(−3)∗(−5)
x3∗y2∗z=(−2)3∗(−3)2∗(−5)
x>y>z
In this situation, option A) is a possible answer.
Case 2:
When x=2 and y=3 and z=5, then:
x3∗y2∗z=(2)∗(2)∗(2)∗(3)∗(3)∗(5)
x3∗y2∗z=(2)3∗(3)2∗(5)
x<y<z
So, option B) is a possible answer as well.
Case 3:
When x=−2 and y=3 and z=−5, then:
x3∗y2∗z=(−2)∗(−2)∗(−2)∗(3)∗(3)∗(−5)
x3∗y2∗z=(−2)3∗(3)2∗(−5)
x<y and y>z
In this situation, option C) is a possible answer.
Case 4:
When x=2 and y=−3 and z=5, then:
x3∗y2∗z=(2)∗(2)∗(2)∗(−3)∗(−3)∗(5)
x3∗y2∗z=(2)3∗(−3)2∗(5)
x>y and y<z
Therefore, option D) is also a possible answer.
Hence, the correct answers are Option A), Option B), Option C), and Option D).
