Question

How do you express `x^2 y^3 t^-4 z^-6 w` with positive exponents?

Answer 1

`(x^2y^3w)/(t^4z^6)`

Explanation:

Using the `color(blue)"law of exponents"`

`color(orange)"Reminder " color(red)(|bar(ul(color(white)(a/a)color(black)(a^-m=1/a^m)color(white)(a/a)|)))`

We can now write the expression as

`x^2/1xxy^3/1xx1/t^4xx1/z^6xxw/1`

`=(x^2xxy^3xx1xx1xxw)/(1xx1xxt^4xxz^6xx1)=(x^2y^3w)/(t^4z^6)`
