Yes. If we don't see an exponent, the exponent is understood to be one. Just like if we don't see a sign, the sign is assumed to be positive. This in no way constricts or limits the variable. The variable can still be anything at all. But assumptions like this are part of mathematics. How tedious would it be to have to write "x1" for each x? In any case, x1 = x so it is almost pointless.
Yes, because if the variable (hypothetically speaking) is 1 (and it can be any number in the world, but 1 is an example), and the exponent (power) is 1, there is only one number to multiply, therefore, the number can only be by itself. If it is squared (to the second power) then you multiply the variable against itself (in this case, 1 X 1), but if the variable doesn't have an exponent, it is assumed to be to the power of one. Take the number 2, for example. If 2 is the variable, x, and x is alone, and you multiply how big the number is of the exponent, and because there is none, it is to the first power.
X squared looks like this: x X x
X (a.k.a. x to the first power) looks like this: x
If there is no exponent, you only multiply what is there, which there is only one variable, so it is assumed to be to the first power. If it were squared, or to the second power as demonstrated above, you would multiply x by itself. If you count the variables in the equation, x squared has two x's, while x alone has only one x in the equation. Because there is only one x, and the exponent represents how many of that number (in this case, x) you multiply by itself, x is assumed to be to the first power, or to the power of one.
define
It depends on the power to which the single variable is raised in that one term.
you first look at the varaibles and their power if there is more than one variable then you will have how ever many variables there are that's how many separate answers there will be also, if you have a number to the power or 2 then there will be two answers for that ONE variable... if you have a number to the power of 8 then you will have eight answers for the one variable.
No. An expression can have a variable exponent (for instance, 2 to the power x, or x to the power y), but that is no longer a polynomial.
degree is the power of variable.. in polynomial it is the highest power of the variable, in differential equations it is the highest derivative, etc..
A variable is usually assumed to represent an unknown quantity. You don't need to "do" anything special to your variable.
It is a variable which, under processes of the experiment or study, does not change or is assumed constant.
A variable is usually assumed to represent an unknown quantity. You don't need to "do" anything special to your variable.

For an algebraic function in one variable, as many as the highest power of the variable.

A: A variable power supply has no disadvantage since it can replace a fix power supply. The disadvantage will rest with the additional cost to make one.

-- If the equation has only one variable (like 'x' or 'y'), and the only power of the variable anywhere in the equation is '1', then the equation has one solution. -- If the variable appears raised to powers higher than '1', then there are as many solutions as the highest power of the variable. -- If the equation has two or more variables, then there are an infinite number of solutions.
This means that your power is a variable. Just like your regular term can be a variable the power can also be a variable. Ex. 3n 7n 2357n
