- Why is x^-1 = 1 x? Whats the logic behind it? Like, what does . . . - Reddit
Every real number x has a unique multiplicative inverse x-1 that satisfies xx-1 = x-1 x = 1 This is a fundamental fact about the real numbers, which itself follows from the corresponding fact about the rational numbers 1 x is just another notation for x-1
- Multiplicative inverse - Wikipedia
In mathematics, a multiplicative inverse or reciprocal for a number x, denoted by 1 x or x −1, is a number which when multiplied by x yields the multiplicative identity, 1 The multiplicative inverse of a fraction a b is b a
- Why is $x^{-1} = \\frac{1}{x}$? - Mathematics Stack Exchange
Substitute $a$ by $1$ and $b, c$ by $x$, we find both definition of $\frac{1}{x}$ and $x^{-1}$ reduce to the unique $y$ in $Y$ (if exists) such that $yx = 1 = xy$ As a result, $\frac{1}{x} = x^{-1}$ whenever they make sense
- What exactly is the difference between x++ and x+1?
x + 1 returns the value of x + 1 x++ returns the value of x, and as a side effect the value of x is incremented at some point, not necessarily immediately This means you can have:
- Simplify x - 1 x - GeeksforGeeks
Simplify x - 1 x Solution: Given, x - 1 x =>By using LCM method => \frac{x x-1}{x} => \frac{x^2-1}{x} By the formula (a+b)(a-b)=a 2-b 2 The formula is derived as =>(a+b)(a-b) =>a a - ab + ab - b b Cancelling -ab and +ab =>a 2 - b 2 As per the derived algebraic formula the solution would be => \frac{(x+1)(x-1)}{x} Sample Problems Question 1
