Logarithmic Property of Inequality: If b, x, and y are positive real numbers with. b > 1, then logb x > logb y if and only if x > y, and logb x < logb y if and only if. x < y. You can also solve an inequality by taking a logarithm of each side or by exponentiating. Solving an Exponential Inequality. Solve 3x < 20.

We have ln(2) is the area of the region shown in the picture on the left above and ln(1=2) is minus the area of the region shown in the picture on the right above. I do not have a formula for ln(x) in terms of functions studied before, however I could estimate the value of ln(2) using a Riemann sum.

Suppose we pick a number, 8 say. Suppose we find its logarithm to base 2, to evaluate log2 8. Suppose we now raise the base 2 to this power: 2log2 8. Because 8 = 23 we can write this as 2log2 23. Using the laws of logarithms this equals 23log2 2. which equals 23 or 8, since log2 2 = 1.

Solve: log 8(x2 14) log 8(5x) Solution: x 7. or x 2. It appears that we have 2 solutions here. If we take a closer look at the definition of a logarithm however, we will see that not only must we use positive bases, but also we see that the arguments must be positive as well. Therefore -2 is not a solution.
