What else can I help you with?
Is the set of nonzero integers closed under division?
The set of nonzero integers is not closed under division. This is because dividing one nonzero integer by another can result in a non-integer. For example, ( 1 \div 2 = 0.5 ), which is not an integer. Therefore, the result of the division is not guaranteed to be a member of the set of nonzero integers.
Is the quotion of any two nonzero integers is a rational number true?
The definition of a rational number is the quotient of any two nonzero integers.
Is the quotient of two nonzero integers a rational number?
Yes.
Is the quotient of two nonzero numbers never a rational number?
The quotient of two nonzero integers is the definition of a rational number. There are nonzero numbers other than integers (imaginary, rational non-integers) that the quotient of would not be a rational number. If the two nonzero numbers are rational themselves, then the quotient will be rational. (For example, 4 divided by 2 is 2: all of those numbers are rational).
Is it true that for any nonzero integers the product and quotient have the same sign?
Yes, it is.
Is the quotion of any two nonzero integers is a rational number true?
The definition of a rational number is the quotient of any two nonzero integers.
Is the quotient of two nonzero integers is also an integer?
No.
Is the quotient of two nonzero integers a rational number?
Yes.
Is the quotient of any two nonzero integers is an integer?
Usually not.
Is the quotient of two nonzero numbers never a rational number?
The quotient of two nonzero integers is the definition of a rational number. There are nonzero numbers other than integers (imaginary, rational non-integers) that the quotient of would not be a rational number. If the two nonzero numbers are rational themselves, then the quotient will be rational. (For example, 4 divided by 2 is 2: all of those numbers are rational).
How many significant digits are in 1581.7812?
Eight - all nonzero integers are significant.
Is any two nonzero integers the product and quotient have the same sign?
True.
Is it true that for any nonzero integers the product and quotient have the same sign?
Yes, it is.
How many significant figures are in 789?
Three. All nonzero integers are significant.
What can you conclude if a and b are nonzero integers such that a divisible by b and b divisible by a?
That a = ±b
Is it true that for any two nonzero integers the product and quotient have the same sign?
yes
How many significant digits does 4.450 have?
Five. Zeros that are after the decimal and are after nonzero integers are always significant.
