Thus, the equation 2 2x+7 = 2 15 can be simplified to 2x + 7 = 15. Because they are the same, the base of each exponent on both sides of the equation can be ignored. Exponents typically take the form of base exponent.

This question may seem daunting due to its exponential form, but it can be easily broken down. This question tests your understanding of solving algebraic equations. Question 3, “2 2x+7 = 2 15.” The correct answer is “4.” Answer choice ⅓ can also be eliminated immediately because Hiroko is not one of the 3 officers which is represented in the ⅓ answer choice. Note, answer choices 0 can be eliminated right away because Hiroko is not an officer, meaning that his chances of being chosen as a representative are greater than 0. Since Hiroko is not an officer of the club, we know that he is included as one of the 32 possibilities, meaning that the probability of him being chosen is 1/32, which is the correct answer. Out of these 32 possible people, each person has the same chance of 1, since they are an individual, of being chosen randomly as the representative.
