You can do absolutely anything with an algebra variable that you can do with a number. You can add them, subtract them, multiply them, divide them, take their root, apply exponents . . . you get the idea. But there's a catch: While you know that 22= 4, there's no way of knowin...
I met a hard problem from Algebra which somehow wasn't that hard despite the exponents and fractions. We finished after half an hour passed. I was back to needing help on homework a week later. I told him - and myself - that we would one day stop these little tutor sessions soon, ...

When you have a negative exponent, then that means you take the reciprocal of what is raised to the exponent, and the exponent becomes positive. Some examples to clarify: x-2 = 1/(x2) 1/(x-2) = x2 (x-2)/(y-3) = y3/x2 <=== since both x and y have negative exponents,...
ex has some handy properties that make it very easy to manipulate algebraically. Because of the laws of exponents, we know that: Why Use Natural Exponential Functions? We don’t just use the natural exponential function because it makes algebra become easy, though. It’s also an accurate mode...
