# How to solve for x with logarithms

logarithms are used to solve for x when x is an exponential. Logarithms allow us to write a problem in terms of numbers that are easier to work with. They also help simplify expressions that are made up of exponential factors: For example, we can write the number 5 as the log of 2 because 5 = 2x + 1.

## How can we solve for x with logarithms

We can also express negative numbers as logarithms: -5 = -5x + 1. In general, logarithms are used to make expressions more manageable and easier to work with. When a base (e.g., 10) is raised to a power (e.g., 10^2), it becomes an exponential value (10^3). For exponents with very small values, logarithms are often used instead of exponents.

To solve for x using logarithms, we replace each logarithm with the log of both sides (loga) in the equation. For example, if we have a log(2x) term in an equation, we would replace that log(2x) with log(2) on both sides. This gives us 2x. Then we can simplify and solve for x. It is important to realize that logarithms are not multiplication by a constant, so they do not add anything to equations or simplify them. They simply change the sign on one side of an equation by converting it from positive to negative or vice versa. While this may sound confusing at first, it is easy to get used to once you start working with logarithms regularly.

Logarithms are one of the most important and useful ways to solve for a number when you know it’s close to 1, but not exactly equal. To solve for x with logarithms, you take the log of both sides of the equation: The y-intercept is then determined by taking the natural log of both sides And, the slope is determined by taking the slope of the line perpendicular to the y-axis and connecting those points (see picture) This technique is used every day in every field. For example, if you are trying to find the slope of a line that shows how fast an object is moving, you would take a measurement at two points along the line and use these measurements to calculate both height and velocity.

*Well, I guess with the latest update now we have to pay for the app plus to see the step by step and that is a big no. But it was fun while it lasted. So, I might uninstall. Great app, got be pass some really thought problems when helping my kids with this new core teaching.*

*The most useful app in the world. Some people say that this app doesn’t recognize numbers, but it’s false. If you take photo correctly this app may save you from any teacher lol. It perfectly explains everything and it’s easy to use! I definitely recommend it!*
