If the monomial (- 1 / 7X ^ 3N + 2) y ^ 4 is the same as (5x ^ 8) y ^ 2m-2, then n = () M = ()

If the monomial (- 1 / 7X ^ 3N + 2) y ^ 4 is the same as (5x ^ 8) y ^ 2m-2, then n = () M = ()

If a monomial is of the same kind, the index of the independent variable should be the same,
Your topic is not very clear about the index,
I've taken everything after ^ as an index,
For the independent variable x, 3N + 2 = 8, the solution is n = 2
For the independent variable y, 4 = 2m-2, the solution is m = 3
The results are as follows
If the monomial (- 1 / 7X ^ 3N + 2) y ^ 4 is the same as (5x ^ 8) y ^ 2m-2, then n = (2) M = (3)

Write the four degree monomial with coefficient - 4 and letters a, B

-4a²b²
-4ab³
-4a³b

The coefficient is minus five-thirds, and the letter is ab. how many monomials are there

Negative five thirds a ^ 3B negative five thirds a ^ 2B ^ 2 negative five thirds AB ^ 3
