Log in math problem without a calculator?
Can anyone explain how to solve this: Find log (base 
1 / 16 without calculator Please explain this in detail for me.
8 ^ x = 1 / 16, you know that log base x (z) = y means x ^ y = z, then log bast 8 1 / 16 is the equation 3x ^ 2 = 1 / 16, 8 is 2 ^ 3, then 8 ^ is 2 x 2 ^ 3x = 3x ^ 2 ^ -4, 1 / 16 is 2 ^ -4 because 2 ^ 4 = 16 and 2 ^ -4 = 1 / 16 3x = -4, with the same basis that you can define powers equal to the other x = -4 / 3, resolve for x
