Why -4 x (-4) = 16 not -16? Simple...

Mathematics

Illusion [34]3 years ago

The reason why it is a positive 16 and not a negative 16, is because when you multiply a negative number with another negative number  you will always get a positive number. But, if you multiple a negative number with a positive number, you will get a negative. So, in order for you to get a -16, the equation would have to be -4*4=-16.

Let A= {a,b,c,d,e} and let B= {1,2,3,4,5} determine n(AxB)
777dan777 [17]

n(AxB) = 25

Step-by-step explanation:

AxB in sets is called Cartesian product. And is defined as a set of ordered pairs (a,b) where a belongs to A and b belongs to B.

Given

A = {a,b,c,d,e}

B = {1,2,3,4,5}

The number of elements for Cartesian product of two sets is determined by:

n(AxB) = n(A) * n(B)

Here

n(A) = 5\\n(B) = 5

So,

n(AxB) = 5*5 = 25

Hence,

n(AxB) = 25
