Let's solve exponential equations! Chegg Trig & Precalculus Office Hour! @blackpenredpen

Uploaded April 2025 | Updated September 2026, 2 weeks ago

Today, we will focus on solving various types of exponential equations and also their application problems. Thanks to everyone who showed up to the live stream and asked the questions in the chat. Thanks to Chegg for the opportunity. We will have more virtual office hours in various subjects. Check out che.gg/3E2AZRw

Lets solve exponential equations! Chegg Trig & Precalculus Office Hour!

x=x+1 has absolutely no solutions, how about sqrt(x)=x+1?

So you want another logarithm triangle (w/ law of cosines this time!)

How many square roots does the 2x2 zero matrix have?

Solving a deductive puzzle from Berkeley mini Math Competition

Volume of revolution (single integral vs triple integral)

Using Feynmans technique TWICE! (the integral of sin^3(x)/x^3 from 0 to inf)

when your calculus test has only one problem

Is this equation solvable? x^ln(4)+x^ln(10)=x^ln(25)
