In this video, we break down 5 different types of exponential equations ranging from basic base matching to more advanced substitution methods. These are essential for anyone preparing for the SAT, ACT, GMAT, or a high school algebra final.
00:00 Intro & 1st Problem 4^(3x-3) = (1/8)^(5-x) (Matching Bases)
01:15 2nd Problem 5^(x+1) + 5^x = 150 (Factoring/Simplifying Method)
01:52 3rd Problem 3^(x+1) - 4 · 3^(x-1) = 45 (Factoring/Simplifying Method)
03:02 4th Problem 9^(x-2) · 2^(2x-1) = 8 (Different bases with zero exponent)
04:43 5th Problem 2^(-x) + 3 · 4^(-x) = 10 · 8^(-x) (The Quadratic Substitution Trick)
