Answer:A=62AED B=93 C=155
Step-by-step explanation:
You add all of the numbers to split between (2,3,5) you get 10
then you divided 310 by 10 which is 31
then you times 2 by 31=62 (a)
3x31=93 (b)
5x31=155 (c)
Answer:
By closure property of multiplication and addition of integers,
If
is an integer
∴
is an integer
From which we have;
is an integer
Step-by-step explanation:
The given expression for the positive integer is x + x⁻¹
The given expression can be written as follows;

By finding the given expression raised to the power 3, sing Wolfram Alpha online, we we have;

By simplification of the cube of the given integer expressions, we have;

Therefore, we have;

By rearranging, we get;

Given that
is an integer, from the closure property, the product of two integers is always an integer, we have;
is an integer and
is also an integer
Similarly the sum of two integers is always an integer, we have;
is an integer
is an integer
From which we have;
is an integer.
