WebJul 17, 2024 · If you know the exponent and want to find out the power, remember that e x = power. This is called the anti-log function. Thus, if you know the exponent is 2, then e 2 = 7.389056. On your calculator, the anti-log can be located … WebSometimes, a good solution is to convert both equations to linear equations by using exponent laws and then canceling out all the exponents at once with a logarithm. Generally, the initial exponents' bases will either all be identical, or one is a perfect square, cube, etc. of the other. Here is an example of that procedure. WebAs percusse and GEdgar point-out in there comments that the reason this seemingly simple equation is not solvable using simple algebra lies in the fact that that the LHS of $2^x = x^2$ is a transcendental function. i.e. it cannot be expressed as a polynomial. Actually the closest it can come to in a "polynomial" form is its Maclaurin series form (see below). csi miami shattered cast
