"A)3^9",
"B)3^12",
"C)3^27",
"D)3^30"
] | D | Solution:
We know that x=3^27
which implies x^x = (3^27)^(3^27) = 3^(27 * 3^27) [because (x^y)^z = x^(y*z))]
so 3^(3^3 * 3^27) = 3^(3^(3+27)) [because x^a * x^b = x^(a+b)]
therefore x^x = 3^(3^30)
Given that x^x=3^k
so 3^(3^30) = 3^k
Since the base is same the exponent will also be same
therefore k = 3^30
