Question

Solve 2^(x + 3) = 7 its Solving Exponential Equations with Unequal Bases

Answer 1

take the log of both sides. Then, because of the properties of logs, you can take the exponent down, so it looks like this:
(x+3) log 2 = log 7
then just solve for x, by dividing both sides by log 2, then subtracting 3. Always be sure to check your answer.
