Question

If log2 = 0.301 then find the number of digits in `2^(1024)`.
A. 307
B. 308
C. 309
D. 310

Answer 1

Correct Answer - C
Let x=`2^(1024)`
` Rightarrow x= log2^(1024)`
` = 1024 log2 = 1024 ( 0.301)`
` Rightarrow logx = 308.22`
The characteristic is 308
The number of digits in `2^(1024) " is " 309` .
