Seventh grade math problems (to process!) 1. Given A-2 + B-3 = 0, find the value of B to the second power of 3AB + 2Ab (the second power of B) - the second power of 4A (the second power of a) 2. If a + B and A-B are opposite numbers, simplify the power of 2008 of a + the power of 2008 of B + the power of 2008 of a - the power of 2008 of B 3. How thick is a piece of paper with a thickness of 0.1 mm if it is folded 20 times? How many floors is it? (to be precise, suppose a floor is three meters high) 4. Known: M = m + m to the power of 2 + m to the power of 3 +... + m to the power of 200 (I) when m = 1, find m; (II) when m = - 1, find m; (III) when M-0, find M 5. If the n-th power of (- 4) is greater than 0 and the m-th power of (- 4) is less than 0, compare the m-th power of (- 1) + (- 1) with the n-th power of 3 + (- 3) 6. A / A + B / B + C / C = - 1, find the value of AB / AB + BC / BC + ABC / ABC To write the process! Well written, give points!

1) A-2 + B-3 = 0, so a = 2, B = 3
2) A + B and A-B are opposite numbers, so a + B = 0 and A-B = 0. A = b = 0
3) 1 times 2 to the 20th power
The answer is 104857.6 mm, or 104.8576 M
104.8576/3 about 35 floors
4) When m = 1, M = 1 + 2 + 3 + 4 + +200=20100
When m = - 1, M = - 1 + 1-1 + 1 +1=0
When m = 0, M = 0
5) The n-th power of (- 4) is greater than 0, and N is even
The m power of (- 4) is less than 0, and M is odd
M power of (- 1) + n power of (- 1) = 0
The nth power of 3 + (- 3) > 0
So the n-th power of 3 + (- 3) n-th power > - 1 m-th power + (- 1) n-th power
6) A / A + B / B + C / C = - 1, indicating that two of them are negative
AB / AB + BC / BC + ABC / ABC = 0
