Question

What is the number of digits in 333? Given that log3 = 0.47712?
A) 12
B) 13
C) 14
D) 15

Answer 1

Answer:   B) 13 

Explanation:

 Let   Let x=(333) Let x=333 = (33)3333

 

 Then, log(x) = 33 log(3)logx = 33 log3  

 

= 27 x 0.47712 = 12.88224 

 

Since the characteristic in the resultant value of log x is 12

 

∴∴The number of digits in x is (12 + 1) = 13 

 

Hence the required number of digits in 333333is 13.
