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 = 7 b = 7, x = 343 x = 343, and y = 3 y = 3. Substitute the values of b b, x x, and y y into the equation by = x b y = x.
Rewrite as an equation. Rewrite log7 (343) = x log 7 (343) = x in exponential form using the definition of a logarithm. If x x and b b are positive real numbers and b b does not equal 1 1, then logb (x) = y log b (x) = y is equivalent to by = x b y = x. Create equivalent expressions in the equation that all have equal bases.
The below is the work with steps to find what is log base 7 of 343 shows how the input values are being used in the log base 7 functions. Formula: log b (x) = y, if b y = x Input: x = 343 b = 7 Solution: y = log 7 343 = log 7 7 3 = 3 log 7 7 = 3 x 1 log 7 343 = 3 log 7 (343) = 3
