A very special island is inhabited only by knights and knaves. Knights always tell the truth, and knaves always lie. You meet four inhabitants: Dave, Rex, Bart and Zoey. Dave tells you that Bart could say that Rex is a knave. Rex claims, “I would tell you that Bart is a knave.” Bart claims, “Only a knave would say that Zoey is a knave.” Zoey claims, “I and Dave are different.” Can you determine who is a knight and who is a knave?

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!

sure i'm up for it
