Find the value of X in the exponential equation. 8^(2x-6) = 16^(2x-3).x = 2. Find the value of X in the exponential equation 1/16 = 8^(x-3). x = (Answer should be in a fraction form, i.e 1/2) The Correct Answer and Explanation is : Let’s solve both exponential equations step by step. Problem 1: [8^{(2x-6)}

 Explain the major difference between statistical and nonstatistical sampling. What are the three main parts of statistical and nonstatistical methods? (Objective 15-2) Audit sampling methods can be divided into two broad categories: statistical sampling and nonstatistical sampling. These categories are similar in that they both involve three phases: 1. Plan the sample 2. Select the
