If logxy = 100 and log2x = 10, then the value of y is:

Question:
If logxy = 100 and log2x = 10, then the value of y is:

[A].

210

[B].

2100

[C].

21000

[D].

210000

Answer: Option C

Explanation:

log 2x = 10         x = 210.

logxy = 100

y = x100

y = (210)100     [put value of x]

y = 21000.
