Rational numbers are numbers that can be expressed as a fraction (ratio). Irrational numbers can not be expressed like that (like sqrt(2)).
To prove your statement, assume the opposite until you have a contradiction.
If the result of adding them would be rational, then your irrational number can be expressed as the difference of two rational numbers, which itself is also a rational number. That cannot be, because it should be an irrational number. This contradiction forces that rational + irrational = irrational.
You can reason the same way for multiplication. Suppose rational * irrational = rational, you find that your irrational can be expressed as the fration of two rationals, which is a contradiction.
Answer:
2 and 8: negative and positive 4
10 and 12, sqrt 120, which simplifies to 2 sqrt 30
Step-by-step explanation:
apparently geometric mean... is taking the product... and square rooting it? okay
The answer is 5 to this expression
$540
6% = .06
“of” = multiply
so 6% of 9000 can be written as .06 x 9000 , which is 540
