This formula states that the log of a number with respect to one base is equal to the log of the same number with respect to another base multiplied by the log of the new base with respect to the old base. So, if we want to solve for x in our example equation above, we can plug in our known values and solve for x using algebra.2log₃x=6⇒log₃x=3⇒x=33Since we now know that 3 was raised to the third power in order to produce 9 (our exponent), we have successfully solved for x in this equation!Common and natural logarithms are two other ways that exponents can be solved for without using the change of base formula. Common logarithms use bases of 10, while natural logarithms use bases of e (approximately 2.71828182845904). To solve for x in equations using these types of logs, all you need to do is take the inverse function of each side. For example, if we want to solve10log₁₀x=100we can simply take the inverse common log function of both sides.This tells us that 100 must have been produced when 10 was raised to some power - but what power? Well, we can use algebra once again!10log₁₀x=100⇒log₁₀x=10⇒x=1010Now we know that 10 was raised to the 10th power in order to produce 100. And just like that - we've solved another equation for x using logs!While solving equations with logs may seem daunting at first, there's no need to worry - with a little practice, you'll be a pro in no time!

One of the most common types of algebraic equations is the multi-step equation. These equations require you to take more than one step in order to solve them. However, if you follow a few simple steps, you'll be able to solve any multi-step equation with ease. The first step is to identify the parts of the equation. In a multi-step equation, there will be an equal sign (=) separating the two sides of the equation. The side with the equal sign is called the "right side" and the other side is called the "left side". On either side of the equal sign, there will be one or more terms. A term is simply a number, variable, or product of numbers and variables. In order to solve an equation, you need to have an equal number of terms on each side of the equal sign. The next step is to use inverse operations to isolate the variable on one side of the equation. An inverse operation is an operation that undoes another operation. For example, addition and subtraction are inverse operations because if you add a number and then subtract that same number, you are left with the original number. Similarly, multiplication and division are inverse operations because if you multiply a number by a certain value and then divide it by that same value, you are left with the original number. You can use inverse operations to solve equations by isolating the variable on one side of the equation. Once you have isolated the variable on one side of the equation, you can solve for that variable by using basic algebraic principles. Remember that in order to solve for a variable, you need to have an equal sign (=) between that variable and what remains on that side after all other terms have been simplified. For example, if you have an equation that says "5x + 10 = 15", you would solve for "x" by subtracting 10 from each side and then dividing each side by 5. This would give you "x = 1". You can use this same method to solve for any variable in a multi-step equation. following these simple steps, you'll be able to solve any multi-step equation with ease!

Solving for exponents can be a tricky business, but there are a few tricks that can make it easier. First, it's important to remember that exponents always apply to the number that comes immediately before them. This means that, when solving for an exponent, you always want to work with the term that is being exponentiated. In addition, it can be helpful to think of solving for an exponent as undoing a power function. For instance, if you are solving for x in the equation 9^x=27, you are really just asking what power function will produce 9 when applied to 27. In this case, the answer is x=3. By understanding how exponents work and thinking of them in terms of power functions, you can make solving for exponents much simpler.

One of the best apps that's why I gave 5 stars. It had helped me do my homework and assignments plus the solving step made it for easier me to understand it. Very nice app literally solves all math equations, but try to developed the feature to solve word problems

Teachers may say that using this is cheating, but honestly if you look a little closer, it's so much easier to understand math if you look at how they did it! I have learned math through this app better than my teacher explaining it 200 times over to me. I WILL SAY THOUGH that the app plus is kind of annoying, it doesn’t bother me about it or anything but if you try to make it explain further you have to purchase it. It's fairly easy to understand without further explanation though.
