Best Answer

Use the LCM for their coefficients.

Use each vriable with the LARGEST exponent in each term.

Ex: Find the LCM of 15 x2y5 and 20 x3y4

LCM of 15 and 20 is 60, LCM of x2 and 20 x3 is x3 , LCM of y5 and y4 is y5

So the LCM is 60 x3y5

Find the LCM of the first two numbers and then find the LCM of that number and the third one. That answer will be the LCM of all three.

You need at least two numbers to find an LCM.Two or more numbers are needed to find the Lcm

The LCM is 36.

You need at least two numbers to find an LCM.

It means you are required to "solve" a quadratic equation by factorising the quadratic equation into two binomial expressions. Solving means to find the value(s) of the variable for which the expression equals zero.

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.

The LCM will contain all factors including variables. Look at coefficients and find their LCM. Then IF several terms have a common factor with a differnt exponent, use that variable with the largest exponent. If a variable appears in only one term, it will still be part of the LCM with its exponent. EX Find LCM for 14s3 and 6 ---- ANSWER --- 42s3 Ex Find Lcm for 3x2y , 4y3, and 7x --- The LCM is 84x2y3 biggest exponents even if not in all terms.

Two expressions are "equivalent" if they have the same result for any values of the variable or variables.

An equation if both expressions are equal

Expressions never have equality signs

You can use them to find a variable. Lets say you have two equivalent expressions with the same variable... x + 2x - 42 = 0 2x - 28 = 0 If you combine these equivalent expressions you ahve... x + 2x - 42 = 2x - 28 In all of the expressions you have x = 7 There are also other applications but its confusing to explain.

An expression with a variable.

These two are both similar because they are both expressions.

Two steps.1) Replace any variable by its value. 2) Do the indicated calculations.
