The expressions equivalent to (81x) include (9^2x) (since (81 = 9^2)), (3^4x) (since (81 = 3^4)), and (x \cdot 81). Additionally, (81 \cdot x) and (x \cdot 81) are also equivalent forms. All these expressions represent the same quantity.

Yes, the expression (9x^2 + 81x + 9) is a trinomial. A trinomial is defined as a polynomial with three terms, which in this case are (9x^2), (81x), and (9). Each term consists of a coefficient and a variable raised to a power, fitting the criteria for a trinomial.
An equation if both expressions are equal
To determine which expressions are equivalent, you need to analyze their structure and simplify them if necessary. Equivalent expressions yield the same value for all variable inputs, so you can also substitute specific values to test for equality. If you provide the specific expressions in question, I can help you evaluate their equivalence.
