Question

Write the degree of each polynomial given below:

(i) $xy+7z$ (ii) $x^2-6x^3+8$

(iii) $y-6y^2+5y^8$ (iv) $xyz-3$

(v) $xy+y{z}^2-z{x}^3$ (vi) $x^5{y}^7-8x^3{y}^8+10x^4{y}^4{z}^4$

Answer 1

(i) degree=2 (Polynomial is xy+7z)

(ii) degree=3 (Polynomial is $x^2-6x^3+8$)

(iii) degree=8 (Polynomial is $y-6y^2+5y^8$)

(iv) degree=3 (Polynomial is $xyz-3$)

(v) degree=4 (Polynomial is $xy+y{z}^2-z{x}^3$)

(vi) degree=12 (Polynomial is $x^5{y}^7-8x^3{y}^8+10x^4{y}^4{z}^4$)
