Do you notice a relationship between the exponents? [practice-area rows=2][/practice-area] [reveal-answer q=680972]Show Solution[/reveal-answer] [hidden-answer a=680972] This problem has exponents, multiplication, and addition in it, as well as fractions instead of integers. Now you can subtract y from 3y and add 9 to 9. For instance, given (3+4)2, do NOT succumb to the temptation to say, "Hey, this equals 32+42 =9+16 =25", because this is wrong. "Multiplying seven copies" means "to the seventh power", so this can be restated as: Putting it all together, the steps are as follows: Note that x7 also equals x(3+4). Some important terminology before we begin: One way we can simplify expressions is to combine like terms. Make sure the exponents have the same base. You can view it online here: pb.libretexts.org/ba/?p=36, Find \(-\frac{3}{7}-\frac{6}{7}+\frac{2}{7}\). %PDF-1.6 % Compute inside the innermost grouping symbols first. Then, move the negative exponents down or up, depending on their positions. 2023 Mashup Math LLC. I can ignore the 1 underneath, and can apply the definition of exponents to simplify down to my final answer: Note that (a5)/(a2) =a52 =a3, and that 52=3. Another way to think about subtracting is to think about the distance between the two numbers on the number line. https://www.mathsisfun.com/algebra/variables-exponents-multiply.html, http://www.purplemath.com/modules/exponent.htm, http://www.algebrahelp.com/lessons/simplifying/multiplication/index.htm, For example, you can use this method to multiply.
