Any Takes?
tehno said:2n!/2n
Simple enough?
mathman said:tehno got it right, integral is wrong. In other words m!=m*(m-1)!, where m=2n.

The expression "2n-1" is an algebraic expression where n is a variable. This means that the value of the expression can change depending on the value of n. For example, if n=2, then the expression becomes 2(2)-1, which simplifies to 3.
To simplify "2n-1", you can use the distributive property of multiplication over addition. This means that you can rewrite the expression as 2n+(-1). Then, you can combine like terms (in this case, 2n) to get the simplified expression of 2n-1.
No, "2n-1" is already in its simplest form. The expression cannot be simplified any further because there are no like terms to combine and no common factors to factor out.
The expression "2n-1" can be used to represent various real-life situations that involve a variable. For example, if n represents the number of hours worked and 2n-1 represents the amount of money earned after taking out taxes, then the expression can be used to calculate an employee's salary after taxes.
The main difference between "2n-1" and "2(n-1)" is the placement of the parentheses. In "2n-1", the parentheses are not present, so the expression cannot be simplified any further. However, in "2(n-1)", the parentheses indicate that the expression inside should be simplified first before multiplying by 2. This results in a different simplified expression of 2n-2.
