In what ways the sum of x + x and the product of x × x different with each other ?

x+x refers to x being added

For Eg:

5+5=10

x+x refers to x being multiplied

For Eg:

5*5 = 25

So you can see that the product is greater than sum

Not always though,

For Example take 2+2=4

and 2*2 = 4

Interestingly 2^2 is also equal to 4

Hope this helps!

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.

the answer is c

hope this !
