If the power 0 of (X-5) is meaningless, then x is?

If the power 0 of (X-5) is meaningless, then x is?

When x = 5, the 0-th power of (X-5) is meaningless. Definition: the 0-th power of any two non-zero numbers is equal to 1, which is derived from the power operation. For example: (X-5) ^ 0, it can be understood that (X-5) ^ 0 = (X-5) ^ n / (X-5) ^ n = (X-5) ^ (N-N) = (X-5) ^ 0, so if the 0-th power of (X-5) is meaningless

If the m power of X is 3, the n power of X is 2, then the M + n power of X=____ The 2m-n power of X=____ .

4/3,6
M power of x = 3. N power of x = 2, that is, m power of x = 2, n power of x = 2 / 3
M + n power of x = m power of X · n power of x = 2.2/3 = 4 / 3
2m-n power of x = the square of m power of X divided by the square of n power of x = 2 · 3 / 2 = 6

What is the meaning and law of the second power of 10, the third power of 10, the fourth power of 10 and the nth power of 10
It's about science and technology law

The second power of 10 refers to the multiplication of two 10, the third power refers to the multiplication of three 10, the nth power refers to the multiplication of N 10, and several 0's are added after 10
