Write in Exponential Form log base 2 of 8=3. log2 (8) = 3 log 2 (8) = 3. For logarithmic equations, logb(x) = y log b (x) = y is equivalent to by = x b y = x such that x> 0 x> 0, b> 0 b> 0, and b ≠ 1 b ≠ 1. In this case, b = 2 b = 2, x = 8 x = 8, and y = 3 y = 3. b = 2 b = 2. x = 8 x = 8. y = 3 y = 3.

Logarithm definition. When b is raised to the power of y is equal x: b y = x. Then the base b logarithm of x is equal to y: log b (x) = y. For example when: 2 4 = 16. Then. log 2 (16) = 4. Logarithm as inverse function of exponential function. The logarithmic function, y = log b (x) is the inverse function of the exponential function, x = by.
log 2 (x 2) = [log 2 (x)] [log 2 (x)] Then I'll apply the log rule to move the "squared" from inside the log on the left-hand side of the equation, taking it out in front of that log as a multiplier:
