Answer:
(I) A=5
(ii)
Step-by-step explanation:
(I) A=log2 log2 log4^256+2 logroot2 ^2
A=log2 log2^4+(2/root2)log2^2
A=log2 log2^2^2+4 log2^2
A=log2^2+4
A=1+4
A=5
(ii) Answer:
Log10 (3) = 0.447
So 10^(0.447) = 3
Multiplying 10^40 on both sides :
10^(0.447+40) = 3 × 10^40
10^(40.447) = 3 × 10^40
So number of digits :
= 1 + number of zeros (power of 10)
[we are adding 1 to account for the three.]
= 1+40
= 41 digits.
