For the intersection operation we have to look what elements both sets have in common, in this case both E and L has the number 8. Then the second answer is:
![E\cap L=\lbrace8\rbrace](https://img.qammunity.org/2023/formulas/mathematics/college/pscoekhiscgfpyomjpkw50w48mri06c509.png)
Now, the union operation adds the all elements into a single set without repetition, in this case the first answer is:
![E\cup L=\lbrace-2,1,2,3,6,7,8\rbrace](https://img.qammunity.org/2023/formulas/mathematics/college/3dpx3kbb9nnx0q22ydhz0y6uz9thx3hvn4.png)
