यदि लॉग 2 = 0.30103, 264 में अंकों की संख्या है:
18
19
20
21
Answer: Option C
Explanation:
Its characteristic is 19.
Hence, then number of digits in 264 is 20.
Answer: Option D
ax = by
log ax = log by
x log a = y log b
अगर logx y = 100 और log2 x = 10, तो y का मान है:
210
2100
21000
210000
log 2 x = 10 x = 210.
logx y = 100
y = x100
y = (210)100 [put value of x]
y = 21000.
Log2 16 का मान है:
4
8
16
Answer: Option B
Let log2 16 = n.
Then, 2n = 16 = 24 n = 4.
log2 16 = 4.
x-1/2
logx y = 100
