To determine which of the given expressions are polynomials in one variable and which are not, we need to follow these steps: ### Step 1: Understand the definition of a polynomial in one variable. A polynomial in one variable must satisfy two conditions: 1. The powers of the variable must be whole numbers (0, 1, 2, 3, ...). 2. It must contain only one variable. ### Step 2: Analyze each expression. ...
