Answer:
Sorry if I'm wrong but...…..
I think the first one is an equation and it's a fraction with powers. (4 and 5).
The next one is a fraction and it is to the power of the number above you have to figure out if you have to multiply the powers with the number under it add them and divide or multiply them by the other number.
The third one is a multiplication problem you have to figure out what "r" is to figure it out you have to do 6 to the 2nd power to get r and you have to do 2 to the 6th power to get the other r. Then multiply the numbers together tp get the answer.
Hope this helps!
