In this manner, why do we rationalize?
Rationalization is actually a defense mechanismthat allows you to justify bad behavior or feelings. It's away to distort facts to make things look better than they do– to convince others and yourself that your motives andactions are good, not bad.
how do we rationalize? So, in order to rationalize the denominator, we need to getrid of all radicals that are in the denominator.
- Step 1: Multiply numerator and denominator by a radical thatwill get rid of the radical in the denominator.
- Step 2: Make sure all radicals are simplified.
- Step 3: Simplify the fraction if needed.
Secondly, how do you rationalize denominators?
Rationalize the Denominator."Rationalizing the denominator" is when wemove a root (like a square root or cube root) from the bottom of afraction to the top.
What does it mean to rationalize a number?
