Given :- Find the two-third power of 64
A) A number having 4 as the sum of its digits.
B) A number having 5 as the sum of its digits.
C) A number having 6 as the sum of its digits
D) A number having 7 as the sum of its digits
Answer :-
→ two-third power of 64
→ (64)^(2/3)
→ (4 * 4 * 4)^(2/3)
→ (4³)^(2/3)
using (a^b)^c = (a)^(b * c)
→ (4)^(3 * 2/3)
→ (4)²
→ 16 .
Therefore,
→ sum of digits of 16 = 1 + 6 = 7 .
Hence, Option (D) A number having 7 as the sum of its digits is right answer.
