Question

Simplify.
r^2s^5t^4 / r^2s^2t^5
A. s^3/t^2
B. s^3/t
C. s^2/t^3
D. s/t

Answer 1

\(\large \frac{r^2s^5t^4}{r^2s^2t^5}=\frac{r^2}{r^2}\frac{s^5}{s^2}\frac{t^4}{t^5}\)
now
\(\frac{a^b}{a^c}=a^{b-c}=\frac{1}{a^{c-b}}\)

Answer 2

so @eflatt13 what is \(\large \frac{r^2}{r^2}= \ ?\)

Answer 3

s^3/t?
