FAQs - Frequently Asked Questions
How do you multiply or divide variables with different letters in algebra?
When multiplying variables with different letters, the variables can be written together without the mulitplication sign between them, for example, 2x x 3y = 6xy. For dividing variables with different letters, variables can be written as a fraction, for example, 6x / 2y = 3x/y.
How do you divide algrabraic expressions?
To divide algebraic expressions, use the laws of indices if the variables are the same. The rule is a^m / a^n = a^(m-n), when you are dividing, subtract the powers. E.g. a^5 / a^2 = a^3.
How do you multiply algebraic expressions?
To multiply algebraic expressions, use the laws of indices if the variables are the same. The rule is a^m x a^n = a^(m+n), so when multiplying two terms, add the powers. For example, a^2 x a^3 = a^5.
