Polynomial
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.
A polynomial.
you do not do anything when you add numbers with exponents. you just figure out the answer. it is only if you multiply numbers with exponents, where you add the exponents..
Fractional exponents follow the same rules as integral exponents. Integral exponents are numbers raised to an integer power.
Example: 3x4y2 and 9x3y5 Treat the whole numbers normally. The LCM of 3 and 9 is 9. Choose the highest value of the variables. In this case, the LCM is 9x4y5

If the base numbers or variables are the same, you add the exponents.
A polynomial is any number of the form Ax^n + Bx^n-1 + ... + c. So, multiplying numbers with exponents with any other numbers with exponents in polynomials only results in another, larger polynomial. Since this is multiplication, you could call the resultant polynomial a product.

A polynomial is any expression (i.e. no = sign) that is the sum of several monomials. Subtraction is ok, but to be a polynomial they can't be divided, and they can't be multiplied with parentheses. Polynomials: 5x+4xy; x2+3x-2; 42x-1. Not Polynomials: (10x)/2+4xy; x(x+3); 45. ---- A monomial is one or more numbers or variables multiplied together. For example, 5x, 23, x2, and 4a3b are monomials. The exponents must be natural numbers.

All numbers can be expressed using exponents.
Example: 3x4y2 and 9x3y5 Treat the whole numbers normally. The LCM of 3 and 9 is 9. Choose the highest value of the variables. In this case, the LCM is 9x4y5
For the greatest common factor, you check which variables appear in each of the expressions. In the case of exponents, you take the lowest exponent for each variable. For the least common multiple, you take each variable, whether it appears in all of the expressions involved, or only in some of them. In the case of the exponents, you take the greatest exponent for each variable. If there are numeric coefficients (numbers as products), you take either the gcf or the lcm of those in the usual way.
Numbers written without exponents are called Standard Form.
