Because if you multiply 2 different irrational numbers (like the following)

You will get an irrational answer.
BUT
if you multiply the same square root (which are both irrational, you get a rational number)
Susan can jump at most 104 in during the long jump
<h3>
Inequality</h3>
Inequality is an expression that show the non equal comparison of two or more variables and numbers.
From the table, the average result for females = 8ft 4in = (8 * 12)in + 4in = 100 in
Since Susan could jump no farther than 4 inches more than the average distance for females, hence:
j ≤ 4 + 100
j ≤ 104 in
Susan can jump at most 104 in during the long jump
