This lesson shows how taking logs of both sides of an equation helps solve equations when the variable is in the exponent. Love this lesson!!
Solving exponential equations using logarithms
To solve for x , we must first isolate the exponential part. To do this, divide both sides by 5 as shown below. We do not multiply the 5 and the 2 as this goes against the order of operations! 5 ⋅ 2 x = 240 2 x = 48. Now, we can solve for x by converting the equation to logarithmic form. 2 x = 48 is equivalent to log 2.
Solving exponential equations using exponent properties
For the 2 sides of your equation to be equal, the exponents must be equal. So, you can change the equation into: -2b = -b. Then, solve for "b". Sal does something very similar at about. 3:45. in the video. Hope this helps.

Solving exponential equations using exponent properties (advanced
Start by factoring the base values to get a common base for the exponents. 9=3^2. Thus, 9^m = (3^2)^m = 3^ (2m) 81=3^4. Now your equation can be written as: 3^ (2m-1)*3^ (2m)=3^4. The left side can be simplified further by using properties of exponents: to multiply values with a common base, we add the exponents.

Then, take the logarithm of both sides of the equation to convert the exponential equation into a logarithmic equation. The logarithm must have the same base as the exponential expression in the equation. Use logarithmic properties to simplify the logarithmic equation, and solve for the variable by isolating it on one side of the equation.

Use the multiplicative property of logarithms to expand the left side to get. ln(e3x+2) = ln3 + lne5x−4. Now, apply the logarithms to the exponents. 3x + 2 = ln3 + 5x − 4. Rearrange to get the x-terms on one side. 2 + 4 − ln3 = 5x − 3x. 6 − ln3 = 2x. Finally, divide the 2 on both sides. x = 6 − ln3 2.
