Question 134142
Simplify:
{{{(r^(-3)s^2t^(-4))/(r^0s^(-4)t^(-5))}}} To change the sign of the exponent, move the base and its exponent down (if it is up) or up (if it is down).
{{{(s^2s^4t^5)/(r^0r^3t^4)}}} Combine the like-bases by adding/subtracting their exponents and recall that {{{x^0 = 1}}}
{{{(s^6t)/(r^3)}}}
