The correct answer is:
Option: A , Option: B , Option: C , Option: D
For a set to be closed under multiplication means if two elements are taken from that set then their multiplication must also belong to the same set.
A)
The product of a perfect cube and a perfect cube.
Let a be a perfect cube of "m"
and b be a perfect cube of "n"
i.e.
Hence,
i.e.
Hence, this set if closed under multiplication.
B)
The product of 0 and 0.
when we take the product of 0 and 0 then the resultant is also zero.
Hence, this set is also closed under multiplication.
C)
The product of a whole number and a whole number.
When we multiply a whole number to a whole number then the product is again a whole number.
This set is also closed under multiplication.
D)
The product of a perfect square and a perfect square.
Let us take two elements of the set as x and y
i.e.
and
Hence,
i.e.
Hence, the set is closed under multiplication.
There are 50 candies left in the jar.
What is mean by Subtraction?
Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
There are 79 candies in the Jar.
Aaron remove 29 candies from the jar.
Now,
Total number of candies in the jar =n 79
And, Aaron remove 29 candies from the jar.
Thus, Left candies in the jar = 79 - 29
= 50
Therefore, There are 50 candies left in the jar.
