We have been given 4 expressions. We are asked to choose the expressions, which simplifies to 0.

Let us check our given choices one by one.

1. 8g-8g

8(g-g)

8(0)=0

When we will subtract 8g from 8g, we will get 0. Therefore, expression 8g-8g simplifies to 0.

2. (-2g)-2g

Let us remove parenthesis.

-2g-2g

Upon combining like terms, we will get:

-4g

Since (-2g)-2g simplifies to -4g , therefore, expression -2g-2g is not a correct choice.

3. 5g+(-5g)

Let us remove parenthesis.

5g-5g

Upon combining terms, we will get:

5g-5g=0

Since 5g+(-5g) simplifies to 0, therefore, expression is a correct choice.

4. $\frac{1}{2}g+\frac{1}{2}g-\frac{2}{3}g+\frac{2}{3}g$

Let us combine the terms as:

$\frac{1+1}{2}g-\frac{2}{3}g+\frac{2}{3}g$

$\frac{2}{2}g-\frac{2}{3}g+\frac{2}{3}g$

$g-g(-\frac{2}{3}+\frac{2}{3})$

g-g(0)

g-(0)=g

Since $\frac{1}{2}g+\frac{1}{2}g-\frac{2}{3}g+\frac{2}{3}g$ simplifies to , therefore, expression $\frac{1}{2}g+\frac{1}{2}g-\frac{2}{3}g+\frac{2}{3}g$ is not a correct choice.
