Common-Core Grade 9 - 9 Rational and irrational numbers properties of operations
|
If A is rational and B is irrational, then A+B, A- B and B- A are irrational.
If A and B are both irrational, then A + B, A - B, AB, and \\(\\frac{A}{B}\\) could be either rational or irrational.
If A is rational and B is irrational, then A+B, A-B, and B-A are irrational.
irrational + 10 = irrational
\\(\\sqrt{144} = 12\\)
If A and B are both irrational, then A+B, A-B, AB, and \\(\\frac{A}{B}\\) could be either rational or irrational.
irrational + rational = irrational
If b = \\(\\sqrt{44}\\)then it would be 0 if b = \\(-\\sqrt{44}\\), then it would be \\(2\\sqrt{44}\\)
If A and B are both irrational, then A+B, A-B, AB, and \\(\\frac{A}{B}\\) could be either rational or irrational.
If a=\\(-\\sqrt{54}\\) and b = \\(\\pi\\) then it would be 0
if a=\\(\\sqrt{54}\\) and b = \\(-\\pi\\), then it would be \\(2\\sqrt{54}+2\\pi\\)
