It may be called "the constant term".
Yes. Any number, or expression, is equal to itself. An equation such as:x + 5 = x + 5 is true for ANY value of "x".
A number that is multiplied by itself is called a base when it is written in exponential notation. Exponential notation consists of the number to be multiplied and a numeral in superscript to the right of it to indicate the number of times it is to be multiplied by itself. When the multiplication process is written out in full, the number is called a factor. The number may also be considered a multiplier or multiplicand when the equation is written this way.
Substitute the number in the equation. If the resulting statement is true the number is a solution to the equation.
Solution. A solution of an equation is a number that satisfy the equation. This means that if you replace this number on the equation and check it, the equation will be true. When you solve an equation you can find some roots, but not all of them satisfy the equation. Thus always check your answers after resolving your equation, and eliminate as solution the answers that don't make the equation true or undefined.
You can call it a "number." To distinguish it from a variable expression, you can also call it a "constant."
constant
A constant.
It is called a variable
It is called a constant.
Either called a "term" or a "constant"
It may be called "the constant term".
You're allowed to do that, yes. Whether or not it "solves" any particular equation depends on the equation itself.
This equation is unsolvable as x2 cannot be a negative number as would be suggested by this equation. Any number, even a negative, multiplied by itself will always give a positive number but this equation leaves you with x2 = -48
a root number is a number in which satifies the unknown value of an equation. For example: x² - 1 = 0 the root of this equation would be 1 or -1 since when multiplied by itself, they both equal 1. Therefore, 1 - 1 = 0
Oops! That's not an equation. It has no 'equals' sign ( ' = ' ) in it, so it's just an 'expression' that stands for a number. The number that it stands for depends on the value of 'x', and any time 'x' changes, the value of the expression changes.
A number for which a given logarithm stands is the result that the logarithm function yields when applied to a specific base and value. For example, in the equation log(base 2) 8 = 3, the number for which the logarithm stands is 8.
