Nanometer is a unit of length, which is used to represent the length of a tiny particle. One nanometer is one billionth of a meter, and 10 ^ - 9 meters, which is equivalent to one 60000 of the diameter of a hair. It is known that the length of a certain micro particle is 80 nm. Please use decimal to indicate the length of the particle?

80nm = 0.00000008m

Why is n plus 2 power of a divided by a equal to n plus 1 power of a

This is defined by the power
The N + 2 power of a is the multiplication of N + 2 a's. similarly, the N + 1 power of a is the multiplication of N + 1 A's, which is less than the N + 2 power of a by one a
Then, the N + 2 power of a divided by a is of course equal to the N + 1 power of A

The cubic power of MX minus the cubic power of 2x is equal to 0, and M is equal to

When x = 0, M is any real number
When x ≠ 0, M = 2

If the sum of mx3yp and nxm + 1Y2 is 0, then M-N + 3p=______ ．

The solution is: M = 2n = - 2p = 2, then M-N + 3P = 2 + 2 + 2 × 3 = 10
