Final answer:
The expression (y^3)/10 is a polynomial of degree 3.
Step-by-step explanation:
The expression (y^3)/10 is a polynomial.
A polynomial is an algebraic expression that consists of variables, coefficients, and mathematical operations such as addition, subtraction, multiplication, and exponentiation. In this case, the expression contains a variable y, a constant 10, and the operation of division. The exponentiation of y to the power of 3 indicates that it is a polynomial of degree 3.
