Chapter 4 - Section 4.2 - Exponential Functions - 4.2 Exercises: 61

Answer

$x=\frac{1}{2}$

Work Step by Step

We rewrite the 2 on the right, so that the base is 4 on both sides. $4^x=2=4^{\frac{1}{2}}$ Then we set exponents equal, because the two sides are equal only if the powers are equal too: $x=\frac{1}{2}$
