These terms are called like terms.For example: x and 2x are like terms.But: x3 and 4x2 are not like termsbecause although the variables are the same, the exponents are different.

Terms like 2x and 4x2 are not like terms. In order for terms to be like terms, they must have the exact same variables with the exact same exponents on them. This means that 5x3 and 7x3 are like terms, but 2x and 4x2 are not. To add or subtract like terms, simply add or subtract the coefficients (the numbers in front) and keep the variable part the same. For example, 5x3 + 7x3 = (5 + 7)x3 = 12x3, and 3x2 + 6x2 = (3 + 6)x2 = 9x2. But, since 2x and 4x2 are not like terms, 2x + 4x2 = 2x + 4x2. It just cannot be simplified any more than that.
Yes, monomials can have negative exponents. When a monomial has a negative exponent, it means that the variable or variables in the monomial are in the denominator of the fraction. For example, x^(-2) is equivalent to 1/x^2. Negative exponents indicate that the variable should be moved to the opposite side of the fraction line and the exponent becomes positive.

It means that it has constants and variables that has a form of something like 7x2+2x+5 or something like that. Variables can not be used as exponents though, and exponents have to be whole numbers. Also, variables can not be a denominator.

They are known as like terms.
You can add and subtract coefficients when they occur in like terms, which means they have the same variable. 2x + 3x = 5x (This addition can take place because all of the variables are x, and are therefore like terms.) and 5y - 2y = 3y (This subtraction can take place because all of the variables are y, and are therefore like terms.) However, if the variables differ, they are unlike terms, and you cannot add or subtract the coefficients. For example: 2a + 3b cannot be added because a and b are different variables, and therefore unlike terms. 3c - 2d cannot occur because c and d are different variables, and therefore unlike terms..

No. For purposes of combining "like terms", you need terms that have exactly the same variables, with the same exponents (if there are any).
4y because they have like variables (y) you can just subtract them like normal
If you have the same base on both of the exponents that you are dividing, all you have to do is subtract the exponent. For example if I have a problem like: 66/ 63, your answer will be 63.
