The Addition Property of Exponents. To multiply powers with the same base, add the exponents. e.g. 34 x 37 = 311, x2x3 = x5, and (3x2yz3)(2x5y2z) = 6x7y3z4.
To evaluate expressions with exponents using the order of operations, follow the PEMDAS/BODMAS rules, which stand for Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). First, calculate any expressions inside parentheses or brackets, then evaluate the exponents. After that, perform multiplication and division before finally carrying out addition and subtraction. This systematic approach ensures that each part of the expression is calculated in the correct order.

The distributive property should be used when you need to simplify expressions or solve equations that involve multiplication over addition or subtraction. It is particularly helpful when dealing with parentheses, allowing you to multiply each term inside the parentheses by a term outside. This property can also make calculations easier by breaking down complex expressions into more manageable parts. Use it whenever you see a situation that fits the form ( a(b + c) ) or ( a(b - c) ).
To use the distributive property, multiply the term outside the parentheses by each term inside the parentheses. For example, in the expression ( a(b + c) ), you would calculate it as ( ab + ac ). This property helps simplify expressions and solve equations by distributing a common factor across terms. It's particularly useful when dealing with addition or subtraction within parentheses.

You multiply 5x5 then 9x1.

In many ways. It really depends on the algebraic expression. If several terms are added/subtracted, you can usually combine similar terms (terms that have the same combination of variables). If variables are multiplied, you can combine the same variable, adding the corresponding exponents. Sometimes expressions get simpler if you factor them; sometimes you have to multiply out (in other words, the opposite of factoring). Quite frequently, you have to use a combination of methods to simplify expressions. Take an algebra book, and look at some of the examples.

To find the product using exponential notation, first express each number in exponential form. For example, if you want to multiply ( a^m ) and ( a^n ), you can use the property of exponents that states ( a^m \times a^n = a^{m+n} ). Simply add the exponents together to get the result in exponential notation. For instance, ( 2^3 \times 2^4 = 2^{3+4} = 2^7 ).
An example of how to use the distributive property: If you have 6x(5+4) you multiply 6x by 5 and get 30x. Then you multiply 6x by 4 and get 24x and then you would have 30x+24x which = 54x
When you add or multiply, you can group the numbers together in any combination.
