# How to solve exponents with variables

Exponents can be solved with variables in a couple of ways. First, you can use the product rule and expand the exponent. For example: Expand the left-hand side to find x and then multiply both sides by y: x = y × y You can also solve exponents with variables by factoring out the variable.

## How can we solve exponents with variables

For example: Factoring out the variable gives us: x = 2y + 3 You can also solve exponents with variables by using one of the two methods that we introduced earlier in this chapter. For example: To solve this, we’ll use the distributive property of exponents and expand both sides, giving us x = 2y + 3 and y = 2x. So when we plug these into our original equation, we get x – 2y = 3, which simplifies to y = 3x – 1. That is, when we divide the top and bottom of an exponent by their respective bases, we get a fraction with a whole number on one side. This means that all pairs of numbers that have the same base have the same exponent so that they cancel each other out and leave just one number in their place (that is, a whole number). So for example, 5x + 1 = 6x – 4; 5x – 1 = 6x + 4; and 6x + 1 = 5

If you are solving exponent equations with variables, you will encounter the same problem that you did when you were trying to solve exponent equations with a single variable. This means that you need to find the value of the exponents for each of the variables involved in the equation. Once you have found them, you can then use those values to solve for the unknown variable. When solving this type of equation, there are two main things to keep in mind: First, always make sure that your exponents are positive or zero. You can check this by making sure that all of your values are greater than or equal to 1. If any of them is less than 1, then your equation is not valid and it should be thrown away. Second, be careful when rounding because rounding can change the value of an exponent. If you round too much, then you may end up with an incorrect answer. For example, if you round one tenth to one hundredth, then the value of the exponent will change from 10 to 100. This results in an error in your solution because it is no longer valid. If these things are kept in mind when solving these types of equations, then they become a lot easier to work with.

Exponents with variables can be quite confusing. When you multiply two numbers whose exponents are both variable, you get a result that is also variable. For example, let's say you have the variable x, and the number y = 6x + 5. In this case, the exponent of y is variable because x is a variable. Now let's say you want to solve for y because you know that the exponent of y is 4. How do you solve this problem? You would factor out the variable x from both sides of the equation and find 4y = 4x + 1. This gives you the answer for y because now you know that 4y = 4(x + 1) = 4x –1. When this happens, we say that there is an "intractable" relationship between the variables on one side of an equation when they cannot be separated.

Very good, actually detects the problems, and way better than Microsoft Math. 100% would recommend. But it has a few flaws. The math problem needs to be written well enough to be understood, and I've only tried it for algebra so I don't know if it works for geometry.

Wow this is the easiest way to learn on your own. I'm sure some cheat but it's also great to learn step by step and it's so easy, you may have to take a few pics for it to calculate the answer but I'm sure that may depend on your camera mine isn't so good. I give it 5 start great app
