Same.
This is effectively the same as lining up the decimal points when adding or subtracting ordinary decimal fractions.
It depends on whether you are working with variables. You cannot add terms with variables that have unlike exponents.
You do not. The exponent is only subtracted in division.
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..
yes its really important

When multiplying something with exponents, you add it. When dividing something with exponents, you subtract it.
When adding or subtracting numbers in scientific notation, ensure that the exponents are the same. If the exponents are not the same, adjust one or both numbers to match. Then, add or subtract the coefficients while keeping the exponent the same. Finally, simplify the result if necessary by converting it back to proper scientific notation.

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.
Yes. When you divide one variable with an exponent from another, you subtract the exponents
the unknowns must be the same variable and the exponents have to be the same. examples) x4 + y4 cannot be added because they are not the same variable. x3 + x2 cannot be added because they have different exponents. 3y6 + 5y6 can be added because they have the same variable and exponents. (answer: 8y6)
Fractional exponents follow the same rules as integral exponents. Integral exponents are numbers raised to an integer power.
