Question

In simplified exponential notation, what is the value of `x^3*x^-4*x`?

Answer 1

We will use these three rules for exponents to simplify this expression:

`a = a^color(red)(1)` and `x^color(red)(a) xx x^color(blue)(b) = x^(color(red)(a) + color(blue)(b))` and `a^color(red)(0) = 1`

`x^3 * x^-4 * x = x^3 * x^-4 * x^1 = x^(3-4+1) =x^0 = 1`
