WebThe answer is surprisingly simple! A negative number raised to an odd power is always negative, and a negative number raised to an even power is always positive. For example, (-6)^11 is negative and (-6)^12 is positive. (Note well: when writing a negative number to a power, parentheses should be placed around the negative number.

WebLogarithms are actually decently complex functions. Consider log 4 base negative two. This is equivalent to log4/log(-2). When you allow logs to have negative arguments, then you're dealing with complex numbers, and the logarithm becomes a multi valued function. WebWorking Together. Exponents and Logarithms work well together because they "undo" each other (so long as the base "a" is the same): They are "Inverse Functions". Doing one, then the other, gets us back to where we started: Doing ax then loga gives us back x: loga(ax) = x. Doing loga then ax gives us back x: aloga(x) = x.

WebMultiplying by 1/81 is easier to work out than 1/9 divided by 81. Always remember: dividing by a number is the same as multiplying it by it's inverse. Example: 10/2 is the same a 10*1/2=5. 20/4 is the same as 20*1/4=5. If you want to multiply instead of divide, just take the inverse or reciprocal of the number you want to divide by. WebWhen a number is raised to log whose base is same as the number, then the result is just the argument of the logarithm. i.e., a log a x = x; Here are some examples of this property. 2 log 2 5 = 5; 10 log 6 = 6; e ln 3 = 3; Negative Log Property. The negative logs are of the form −log b a. We can calculate this using the power rule of logarithms.
