Answer:

The correct option is c.

Explanation:

The given expression is


243^{(2)/(5)}

According to the exponential property:


x^(mn)=(x^(m))^n

Using this rule we get


243^{(2)/(5)}=(243^{(1)/(5)})^2


243^{(2)/(5)}=(3)^2
(243^{(1)/(5)}=3)


243^{(2)/(5)}=9

The value of given expression is 9. Therefore the correct option is c.
