$8y+3x^{2}$ The terms in the expression are

$8y\ and\ 3x^{2}$

$8y+3x^{2}$ is obtained by adding the product of 8 and y with the product of 3 x and x

the tree diagram for the expression is given below

$7mn-4$ has two terms 7mn and 4 and the expression is obtained by subtracting 4 from the product of 7,m and n. The tree diagram is shown below.

$2x^2y$ has only one term, that is the expression itself.

The expression is formed by multiplying 4 terms 2, x, x and y. The tree diagrams are shown below
