what is the degree of the monomial 3x²y³?

A) 2

B) 3

C) 5

D) 6

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

In the given monomial, 3x²y³, the exponent of x is 2 and the exponent of y is 3.

Thus, the degree of the monomial is 2 + 3 = 5.

Therefore, the answer is C) 5.
