WebIn other words, an expression raised to a negative exponent is equal to 1 divided by the expression with the sign of the exponent changed. Hence, for any non – zero real … WebNow take the natural logarithm (or other base if you want) of both sides of the equation to get the equivalent equation ln (b)=ln (a^M). Now we can use the exponent property of logarithms we proved above to write ln (b)=M*ln (a). Divide both sides by ln (a) to get ln (b)/ln (a) = M Substituing in for M in our original equation we now see that
WebRule 7: Inverse Property of Exponent Raising the logarithm of a number to its base is equal to the number. Rule 8: Change of Base Formula Examples of How to Apply the Log Rules Example 1: Evaluate the expression … WebA negative exponent helps to show that a base is on the denominator side of the fraction line. In other words, the negative exponent rule tells us that a number with a negative exponent should be put to the denominator, and vice versa. For example, when you see x^-3, it actually stands for 1/x^3. Not too bad right?
