First of all u must be familiar with all the notions used in the sets and venn diagrams. they are as follows:

I hope u know the meanings of all these symbols. If not, tell me I will explain them.
Now I come to the shading of venn diagrams.
For that visit the following link:

Thnk u soo much I now have full understand of venn and sets

Can u pls explain indices also

8^0.25 / 4^-2

I can't seem to solve this

You are welcome,
Now i will solve the indices question.
8^.25= (2^3)^.25
4^-2 = 1/16 = 2^-4
so 2^.75/2^-4
= 2^.75-(-4)
= 2^4.75 (answer)

If u r familiar with the ri=ules of indices then you will understand the working otherwise tell me so I may explain you the basic rules of indices as well.
