Right, my first post, I'll say, "hi" to everybody for a start.
Now for the problem, I would like somebody to come up to me with an answer fast since I only have 4 hours left. = (.
!!!!The numbers in the first statement in the bracket are, powers!!!!
1(2') - 1(2') = 1-1
(1+1)(1-1) = 1-1
1+1 = 1
2 = 1
Now according to our math teacher, the first statement is correct while the other 3 are wrong.
Now help me??!! =(
