Question

Find the degree of the following expression:
$x^5{y}^7-8x^3{y}^8+10x^4{y}^5{z}^4$.

• A. 12
• B. 11
• C. 13
• D. 10

Answer 1

The correct option is C 13

The highest degree among the degrees of different terms of an expression is called the degree of the algebraic expression.

The degree of the term, $x^5{y}^7=5+7=12$
The degree of the term, $-8x^3{y}^8=3+8=11$
The degree of the term, $10x^4{y}^5{z}^4=4+5+4=13$

So, the degree of the expression is 13.
