Rewrite log2 (8) = x log 2 (8) = 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.
31 Ιουλ 2024 · The logarithm in base 2 of 256 is 8. To find this result, consider the following formula: 2 x = 256. The logarithm corresponds to the following equation: log2(256) = x. In this case, we can check the powers of 2 to see if we can find the value of x: 2 0 = 1, 2 1 = 2, 2 2 = 4, …, 2 7 = 128, and 2 8 = 256.

For example, raising 2 to the power of 3 gives 8: displaystyle2³=8. The logarithm of base b is the inverse operation, that provides the output y from the input x. That is, displaystyley=logbx is equivalent to displaystylex=bʸ if b is a positive real number.
30 Ιουλ 2024 · This log calculator (logarithm calculator) allows you to calculate the logarithm of a (positive real) number with a chosen base (positive, not equal to 1). Regardless of whether you are looking for a natural logarithm, log base 2, or log base 10, this tool will solve your problem.
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. Substitute the values of b b, x x, and y y into the equation by = x b y = x.
