Textbook Question
Solve each exponential equation in Exercises 1–22 by expressing each side as a power of the same base and then equating exponents. 6(x−3)/4=√6
Verified step by step guidance1
Recognize that the equation is \$6^{\frac{x-3}{4}} = \sqrt{6}$. The goal is to express both sides as powers of the same base.
Rewrite the right side, \(\sqrt{6}\), as a power of 6. Recall that \(\sqrt{6} = 6^{\frac{1}{2}}\).
Now the equation becomes \$6^{\frac{x-3}{4}} = 6^{\frac{1}{2}}$.
Since the bases are the same and the equation is an equality, set the exponents equal to each other: \(\frac{x-3}{4} = \frac{1}{2}\).
Solve the resulting linear equation for \(x\) by multiplying both sides by 4 and then isolating \(x\).
