In imaginary numbers can you multiply two radicals that have negative values under them that do not square to whole numbers

ElenaW [278]

Yes, you can; based on the inherent assumption that the "two radicals that have negative values" are, in fact, "imaginary numbers" .

Take, for example, the commonly known "imaginary number": "i" ; which represents the "imaginary number" ; " √-1 " .

Since: "i = √-1" ;

Note that: " i² = (√-1)² = √-1 * √-1 = √(-1*-1) = √1 = 1 .

lesya [120]

Based on the data presented, it can be concluded out of the 52 females 26 prefer cats.

<h3>How to read the graph?</h3>

To read the graph we must take into account that the rows refer to the preference of men, preference of women and those who have no preference.

On the other hand, the columns refer to the number of students of both genders who prefer or do not prefer each animal. Additionally, adding all the students of each gender we have the total of the sample.

According to the above, the total sample of female students would be 52.

20 + 26 + 6 = 52

According to the above, the fraction that expresses this relationship correctly is:

$\frac{26}{52}$

Note: This question is incomplete because the graph is missing. Here is the graph.
