Solving an exponential equation

Показать описание
👉 Learn about solving exponential equations. Exponential equations are equations involving exponents. To solve an exponential equation, we express the terms in both sides of the equality sign as single terms. Then, we express the single terms on both sides of the equality sign as powers having the same base. Once, we have expressed the terms as powers of the same base, we can then equate the exponents and hence solve for the unknown variable.

If the terms at both sides of the equality sign cannot be expressed as powers of the same base, then the logarithm of both sides of the inequality sign is taken and with our knowledge of logarithm laws/properties, we can solve for the unknown variable.

raise each side to the (7/3) power. That is the inverse power on the left side so you will be left with x

Why did the 3 become positive when you divided by -1?

Why didn't it change base like log base3 of 7 did?

2:30 Oh, I thought you would right the not equal to sign instead of what you wrote. That thing is not true, right? Then why are you writing the equal sign?
