Stefan says he cannot simplify the expression [tex] \frac{p^{c}}{r^{c}} [/tex]. Complete the statement about Stefan's claim.
Stefan (can, cannot) simplify this expression because the two parts (have, do not have) the same (base, exponent).
[tex] \frac{p^{c}}{r^{c}} [/tex] is the same as:
(p * c)/(r * c)
(p/r)^c
p * c - r * c
(p/r)^c/c
no other expression
