Expert Solution

a)

According of rule, k must satisfied following inequality:

Taking log of both sides

That is k should be at least 6.

b)

According of rule, k must satisfied following inequality:

Taking log of both sides

That is k should be at least 9.

c)

According of rule, k must satisfied following inequality:

Taking log of both sides

That is k should be at least 11.

d)

According of rule, k must satisfied following inequality:

Taking log of both sides

That is k should be at least 12.
