Question

How do you simplify `r^-2 s^-2 t^4`?

Answer 1

`(t^4)/(r^2s^2)`

Explanation:

You need to write the expression so that there are no negative indices.

Remember the law of indices which states: `x^(-m) = 1/(x^m)`

Each base can be moved independently of the others.

`color(red)(r^-2) color(blue)(s^-2) color(brown)(t^4)`

=`color(brown)(t^4)/(color(red)(r^2) color(blue)(s^2))`
