Question

find the value of x²y²z²+x²y-x²y²+15,if x=-2,y=7 and z=-2.​

Answer 1

Step-by-step explanation:

Given expression is xyz + xy - z

1 ) degree of the first term ( xyz )

= 1 + 1 + 1 = 3

2 ) degree of the second term ( xy )

= 1 + 1 = 2

3 ) Degree of the third term ( -z )

= 1

Therefore ,

degree of the expression = highest degree

Answer 2

Step-by-step explanation:

Given expression is xyz + xy - z

1 ) degree of the first term ( xyz )

= 1 + 1 + 1 = 3

2 ) degree of the second term ( xy )

= 1 + 1 = 2

3 ) Degree of the third term ( -z )

= 1

Therefore ,

degree of the expression = highest degree

= 2
