There are two ways to solve this. One is using the definition of logarithms: solve the equation 4x = 16. This can be done by inspection, in this case. The other is to use a change-of-base, to change to a base your calculator can handle. For example, changing to base e: log416 = ln(16) / ln(4)
B5 in base 16.
121 in base 4 = 16 + 8 + 1 (base ten) = 2584 in base 16 = 128 + 4 (base ten) = 132132 + 25 = 157(base 10) = 9D (base 16) = 2131 (base 4)
In base 16 it would be 8630F9
16 is 8 percent of 200. Given: Percentage = 16 ; Rate = 8% Find: Base Formula: Base = Percentage/Rate Solution: Base = 16/8% = 16/0.08 = 200
