This is quite clear when you add measurements, for example, lengths. If you just go ahead and add the numbers, without considering differences in units, you get DIFFERENT RESULTS, depending on the units used. For example, if you add 1 m + 2 m, you get 3 m - but if you express this as 1000 mm + 2 m, you get 1002. 1002 what? Anyway, this isn't the same answer as before, whether you decide that the 1002 represents meters, or mm. So, something is obviously very wrong; there is no way to make sense out of the calculations - unless you FIRST convert to the same units.If you try to add different units ("unlike terms"), for example meters and square meters, the situation gets even worse.

What exactly has the same variable and exponents?

In algebra, expressions that have the same variable and exponents are considered like terms. For example, the terms (3x^2) and (5x^2) are like terms because they both contain the variable (x) raised to the same exponent of 2. Like terms can be combined through addition or subtraction, while terms with different variables or exponents cannot be combined in this way.


Is a pattern where the terms are related by addition and subtraction?

Yes


Is the process of addition and subtraction of radical expression with like and unlike terms the same?

The process is the same for addition and subtraction. The process is totally different for like and unlike terms.


Like terms have the same variable but may be raised to different powers?

No. Like terms should contain the same variable or variables, raised to the same powers. Like terms are those that can be combined by addition or subtraction.


What is a like term of 5x?

A like term of 5x is any term that has the same variable raised to the same power. For example, 3x or -2x are like terms of 5x because they both contain the variable x raised to the first power. Like terms can be combined through addition or subtraction, while terms with different variables or powers cannot be combined.

What is a like term for 8z?

A like term for 8z is any term that contains the variable z raised to the same power. For example, 3z or -5z are like terms because they both include the variable z. Like terms can be combined in expressions through addition or subtraction.


Terms that have the same variables raised to the same powers are called terms?

Terms that have the same variables raised to the same powers are called like terms. Like terms can be combined through addition or subtraction because they represent the same quantity in algebraic expressions. For example, (3x^2) and (5x^2) are like terms, while (3x^2) and (4x) are not.


Are 3x and x like terms in math?

Yes, (3x) and (x) are like terms in math because they both contain the variable (x) raised to the same exponent (which is 1). Like terms can be combined through addition or subtraction, so you can simplify an expression involving both (3x) and (x) by combining them to get (4x).


Arithmetic progression?

This a progression that involves addition or subtraction of successive terms in a sequence.


What is expression in math terms?

It is a collection of terms which are combined using various mathematical operations such as addition, subtraction, multipplication, division, power, inverse, trigonometric functions etc. It does not have an equality of inequality relationship - which would make it an equation or inequality.
