Which of the following expressions has 3 terms?
8x + y - z
xyz
y^3 + 1
the first
first
To determine which of the given expressions has 3 terms, we need to count the number of distinct terms within each expression.
1. 8x + y - z:
To count the terms in this expression, we identify the distinct variables or variable combinations separated by the plus (+) or minus (-) signs. In this case, we have three distinct terms: 8x, y, and -z.
2. xyz:
In this expression, xyz is a single term since there are no mathematical operations or symbols separating the variables x, y, and z.
3. y^3 + 1:
Similar to the first expression, we identify the distinct terms separated by the plus sign. In this case, we have two distinct terms: y^3 and 1.
Therefore, the expression "8x + y - z" has 3 terms, as it contains three distinct variable combinations separated by plus and minus signs.
