Answer:
(d) 1
Explanation:
To evaluate the expression a^((x-y))*a^((y-z))*a^((z-x)), we can simplify it using the properties of exponents.
Using the rule of multiplying exponential expressions with the same base, we can combine the exponents:
a^((x-y))*a^((y-z))*a^((z-x)) = a^((x-y+y-z+z-x))
Simplifying the exponents further:
= a^((x+z-x-y+y-z))
Notice that the terms x and z cancel out, and the terms y and -y also cancel out:
= a^((0))
Any number raised to the power of 0 equals 1:
= 1
Therefore, the value of the expression a^((x-y))*a^((y-z))*a^((z-x)) is 1.
