How to solve for an exponent with log

WebApr 10, 2024 · We can solve exponential equations with base \(e\), by applying the natural logarithm of both sides and then using the fact that \( \ln (e^U) = U \). After solving an exponential equation, check each solution in the original equation to find and eliminate any extraneous solutions (Specifically, \(b^p\) is ALWAYS positive). WebSolve: $$ 4^{x+1} = 4^9 $$ Step 1. Ignore the bases, and simply set the exponents equal to each other $$ x + 1 = 9 $$ Step 2. Solve for the variable $$ x = 9 - 1 \\ x = \fbox { 8 } $$ Check . We can verify that our answer is correct by substituting our …
