Which of the following are terms in this expression? Select all that apply.

Question

1+10u+v3+7v2
7v
9u
7v^2
8u

Answer 1

In the expression \( 1 + 10u + v^3 + 7v^2 \), the terms are the distinct parts separated by '+' signs. The terms in the expression are:

1. \( 1 \) (a constant term)
2. \( 10u \) (a term involving \( u \))
3. \( v^3 \) (a term involving \( v \))
4. \( 7v^2 \) (a term involving \( v^2 \))

Now, looking at the options:

• \( 7v \) is not a term in the expression.
• \( 9u \) is not a term in the expression.
• \( 7v^2 \) is a term in the expression.
• \( 8u \) is not a term in the expression.

Therefore, the only term in the expression from your provided options is \( 7v^2 \).
