Question 3(multiple choice worth 3 points) (07.04) ashley solved the exponential equation 3x+1 = 15 and her work is shown below. what is the first step she did incorrectly? step 1: log 3x+1 = log15 step 2: (x + 1)log 3 = log15 step 3: x + 1 = log 15 over log 3 step 4: x+1 = 2.708050 over 1.098612 step 5: x + 1 = 1.418858 step 6: x = 0.418858 step 1 step 2 step 3 step 4

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
