Hey darence.

Can you show us what you have tried (Hint: try expanding the definitions using log laws for change of base and powers and get an expression with k on one side of the inequality)? - Jan 30th 2013, 04:03 AMdarenceRe: Logarithm
That's my biggest problem. I don't know where to start from with this problem

Hint: log_a(x) = ln(x)/ln(a) [Change of Base Rule] and ln(a^x) = x*ln(a)
