The Relationship between Exponentials and Logarithms To understand a logarithm, you can think of it as the inverse of an exponential function. While an exponential function such as =5 tells you what you get when you multiply 5 by itself times, the corresponding logarithm, =log5( ), asks the opposite question: how many
ACADEMY MATH CHEAT SHEET Rules of Exponents For any nonzero x, x0 = 1. For any integers p and q, x p q = q √ xp = (q x)p. If p is positive this is defined for all x when q is odd and for nonnegative x when q is even. If p/q is negative, the power x p q is never defined for x = 0. Other exponent rules include xr+s = xrxs (xr)s = xrs (xy)r ...
