Inverse Properties of Exponents and Logs (8.6)Base A Base E1. 1. • 2. a x 2. =x • To solve a logarithmic equation such as: • lnx=3 logaARITHMIC FORM • Write the equation in exponential form such as: • Exponentiate both sides • x= exponential form • This procedure is called exponentiating both sides of an equation. • Prpoperties of exponential and Logarithmic equations • if x=y • if x=y
Example probs • x=ln 72 • x=4.277 • lnx=3 • X=20.086 • X=2.81 • 3x=100 • X=33.3
Practice problems • 16lnx=30
