If I build a three story building with a total area of 300 square meters and a land area of 100 square meters, can I get a new house of 100 square meters when I move or demolish?

It's mainly based on the area of the house, * 1.5 or 1, not necessarily, which needs to be negotiated by both parties

Factorization 3 * 199 ^ 2-3 * 201 ^ 2

Originally = 3 * (199 ^ 2-201 ^ 2) = 3 * (199 + 201) (199-201) = 3 * 400 * (- 2)
=-2400

(1) if x0, then / x + Y / = ()
(4) If a > b > 0, then / - A-B / = ()

-x 1-a x+y a+b

45.6*6.7+4.56*31+0.456*20=?

Original formula = 45.6 * 6.7 + 45.6 * 3.1 + 45.6 * 0.2
=45.6*(6.7+3.1+0.2)
=456

The ratio of 5 / 8 to 0.125 is

5 out of 8 vs. 0.125
5/8：1/8
=5：1
=5

How to divide 2 / 3 and 1 / 5, please
Write it down

2/3=10/15 1/5=3/15

27 × 4 / 5 + 27 △ 5

27×4/5+27÷5
=27×4/5+27×1/5
=27×(4/5+1/5)
=27

When x approaches 0, Lim 1 / (2 ^ x-1) = ∞ why?
Do you want to look at the left limit and the right limit separately?

2 ^ X-1 is continuous, and the limit at 0 is 0,
So the answer is infinity
