Can you multiply two different variables?

Can you multiply two different variables?

When variables are the same, multiplying them together compresses them into a single factor (variable). But you still can’t combine different variables. When multiplying variables, you multiply the coefficients and variables as usual.

How do you distribute two variables?

Combine the variables by using the rules for exponents. Multiply each term by 5x. Then multiply the numbers and the variables in each term….How to Distribute Variables

1. Distribute the term outside the parentheses over the terms within.
2. Add the exponents.
3. Complete the distribution.

How do you multiply multiple variables?

To multiply terms, multiply the coefficients and add the exponents on each variable. The number of terms in the product will be equal to the product of the number of terms.

Do you add or multiply first in equations?

Order of operations tells you to perform multiplication and division first, working from left to right, before doing addition and subtraction. Continue to perform multiplication and division from left to right. Next, add and subtract from left to right.

How do you do multiple expressions?

How to Multiply Rational Expressions?

1. Factor out both the denominator and numerator of each expression.
2. Reduce the expressions to the lowest terms possible only if the numerators and denominators’ factors are common or similar.
3. Multiply together the remaining expressions.

Can you divide by a variable?

Each variable is considered separately. When dividing variables, you write the problem as a fraction. Then, using the greatest common factor, you divide the numbers and reduce. You use the rules of exponents to divide variables that are the same — so you subtract the powers.

Can variables be zero?

The nonbasic variables are all equal to zero. Just because a variable is basic, it doesn’t have to be strictly positive. A basic feasible solution is degenerate if at least one of the basic variables is equal to zero.

Why can’t we divide by zero?

The reason that the result of a division by zero is undefined is the fact that any attempt at a definition leads to a contradiction. a=r*b. r*0=a. (1) But r*0=0 for all numbers r, and so unless a=0 there is no solution of equation (1).

Why is 1 divided by 0 infinity?

something/0: The thing is something divided by 0 is always undefined because the value has not been defined yet. So, when do we say this something divided by 0 is infinity? Well, something divided by 0 is infinity is the only case when we use limit. Infinity is not a number, it’s the length of a number.
