Expression in One Variable
The expression in one variable is given as:
a) x + x^2 + 1
b) x y
c) 9y
d) xyz
Explanation:
a) x + x^2 + 1:
This expression consists of three terms. The first term is x, the second term is x^2, and the third term is 1. Here, x and x^2 are both variables raised to different powers. The expression cannot be simplified further as the terms have different powers and cannot be combined.
b) x y:
This expression consists of two variables, x and y, multiplied together. It represents the product of x and y. The expression cannot be simplified further as the variables cannot be combined.
c) 9y:
This expression consists of a constant term, 9, multiplied by the variable y. The expression represents the product of 9 and y. The expression cannot be simplified further as it is already in its simplest form.
d) xyz:
This expression consists of three variables, x, y, and z, multiplied together. It represents the product of x, y, and z. The expression cannot be simplified further as the variables cannot be combined.
Conclusion:
Out of the given options, option 'a' (x + x^2 + 1) is the expression in one variable. The other options either consist of multiple variables or constants. The expression in option 'a' cannot be simplified further as the terms have different powers and cannot be combined.
