Question

of each monomial. see example 1

1. $-7xy$
2. $4x^2y$

Explanation:

Problem 20: Find the degree of \(-7xy\)

Step1: Recall degree of monomial

The degree of a monomial is the sum of the exponents of its variables.

Step2: Identify exponents

For \(x\), the exponent is \(1\) (since \(x = x^1\)) and for \(y\), the exponent is \(1\) (since \(y = y^1\)).

Step3: Calculate the sum

Sum the exponents: \(1 + 1 = 2\).

Step1: Recall degree of monomial

The degree of a monomial is the sum of the exponents of its variables.

Step2: Identify exponents

For \(x\), the exponent is \(2\) and for \(y\), the exponent is \(1\) (since \(y = y^1\)).

Step3: Calculate the sum

Sum the exponents: \(2 + 1 = 3\).

Answer:

The degree of \(-7xy\) is \(2\).
