Simplify the following expression, giving the answer in index notation: 8^12/8^2. question (j)

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?

Consider that lines b and c are parallel. what is the value of x? what is the measure of the smaller angle?

If you measured the width of a window in inches and then in feet with measurement would you have the greater number of units
