Question

1. $4xy^{2}+2xy + 7+11xy - 12xy^{2}$

$degree = $

1. $6xyz^{2}+xyz^{2}+7xy - 16x^{2}y^{2}+10xy^{2}z$

$degree = $

1. $9xy + 9x^{2}-9x^{3}+9x^{2}+9xy - 9xy$

$degree = $

Explanation:

Step1: Identify highest term degree (Q1)

For $4xy^2+2xy+7+11xy-12xy^2$, the term $xy^2$ has degree $1+2=3$.

Step2: Identify highest term degree (Q2)

For $6xyz^2+xyz^2+7xy-16x^2y^2+10xy^2z$, terms $xyz^2$ and $xy^2z$ have degree $1+1+2=4$.

Step3: Identify highest term degree (Q3)

For $9xy+9x^2-9x^3+9x^2+9xy-9xy$, the term $x^3$ has degree $3$.

Answer:

1. degree = 3
2. degree = 4
3. degree = 3
