You can put this solution on YOUR website!
find the LCD for -5/x^2t and x/t^3
--------------
The LCD must contain each of the factors of the denominator in its highest
power.
------------------
You have
x^2 in the denominator so there must be an x^2 factor
you have t and t^3 so there must be a t^3
-----------------
The LCD is x^2t^3
