1]express j! in ∏ notation
Are they just wanting something like \(\displaystyle j! + (j-1)! + (j-2)! +(j-3)!\)...?

shamieh said:f is always multiplied by k.
\(\displaystyle \prod^j_{k=1} n!\)
"Product" notation is a mathematical shorthand used to express the multiplication of multiple terms. It involves using the symbol "x" to represent multiplication and listing all the terms to be multiplied together. For example, 2x3x4 would be written as "product notation" 2, 3, 4.
"Product" notation differs from traditional multiplication in that it is a more concise and organized way of representing multiplication. Instead of writing out all the terms and symbols, "product" notation allows for multiple terms to be written using just one symbol, making it easier to perform calculations and understand complex equations.
"Product" notation is commonly used in algebra and other areas of mathematics where expressions and equations involve multiple terms being multiplied together. It is also frequently used in statistical analysis and in the study of functions and their graphs.
There are several advantages to using "product" notation. It allows for more efficient and organized representation of multiplication, making it easier to understand and perform calculations. It also helps to reduce errors and confusion, especially when dealing with complex equations.
Yes, there are a few rules and conventions to follow when using "product" notation. The terms to be multiplied should be listed in order from left to right, and the use of parentheses can be used to specify the order of operations. Additionally, the symbol "x" should only be used for multiplication and not for variables or unknowns.
