The sum of a rational and irrational number must be an irrational number.
No, 3.56 is not an irrational number. 3.56 is rational.
rational * irrational = irrational.
-Pi is irrational, because it does not terminate or repeat. Whenever you multiply an irrational number by a rational number (-1), the result is an irrational number.
Any irrational number, when multiplied by 0.5 will give an irrational number.
1 and 1125.
1125 is not a prime number because it has more than two factors
An irrational number.
No. The sum of an irrational number and any other [real] number is irrational.
The sum of a rational and irrational number must be an irrational number.
No. Consider:1125 = 45 * 25 = 9 * 5 * 5 * 5 = 3 * 3 * 5 * 5 * 5A prime number is defined as an integer that has no factors, so 1125 does not meet that qualification. It is instead a composite number.
No, 3.56 is not an irrational number. 3.56 is rational.
rational * irrational = irrational.
1125 ends in a 5, so it is divisible by 5. Divide 1125/5 and see what you get. Then find the factors of that new smaller number. This is how you factor numbers.
1125
composite
