Math Help, desperate immediate ten points for first complete, correct and efficient answer.?

ok I'm just having fun with your minds ok, i'm not really desperate.





Describe each set by using set builder notation / set notation


1


a) {1, 2, 4, 8, 16}


b) {121, 144, 169, 196, 225, 256, 289, 324, 400, 441, 484, 529, 576, 625}








2 write an expression using set operations ( union, intersection, subtraction)





a) the set of students in a scholl taking tutorial in at least one of the three subjects.





b)The set of students at the scholl taking both english and math but not science

Math Help, desperate immediate ten points for first complete, correct and efficient answer.?
The first one is the set of the first 5 powers of 2.


The second one was the set of the squares of the numbers from 11 to 25.





2a is the union of the sets of the people taking a tutorial in each individual subject.





2b is the intersection of the english and math students minus the science students.





2c is the union of: english minus (math union science), math minus (english union science) and science minus (english union math). I liked this problem.
