    first, flip \[ p^{-5} \] what do you get ?

    no. just change \[ \frac{p^{-5}}{1} = \frac{1}{p^5} \] notice you flip it upside down and change -5 to +5

    your problem is now \[ \frac{1}{p^5}= \frac{1}{243} \] you can flip both sides, \[ p^5 = 243\]

    you know p*p*p*p*p is 243 to find p we could try factoring 243 or we can try guessing p for example if p=1 we get 1*1*1*1*1= 1 which is too small also if p=2 we would get 2*2*2*2*2= 32 still too small what about p=3?

    3 * 3*3*3*3= 243

    that works. so p is 3
