যদি (64)\(\frac{2}{3}\) + (625)\(\frac{1}{2}\) = 3K হয়, তবে K এর মান -

যদি (64)^{\(\frac{2}{3}\)} + (625)^{\(\frac{1}{2}\)} = 3K হয়, তবে K এর মান -

A 9(2/3)

B 11(1/3)

C 12(2/5)

D 13(2/3)

Correct Answer: Option D

(64)^{\(\frac{2}{3}\)} + (625)^{\(\frac{1}{2}\)} = 3K

or, (4³)^{\(\frac{2}{3}\)} + (25²)^{\(\frac{1}{2}\)} = 3k

or, 16 + 25 = 3K

K = \(\frac{{41}}{3} = 13\frac{2}{3}\)
