anonymous 5 years ago Rationalize the Denominator: √5² ------ 4-√6²

$\sqrt{6^{2}}=6$ so $4-\sqrt{6^{2}}=4-6=-2$

hmm well with the other half of the problem i got my answer to be -5/2 because, i took √5² = 5 then √6² = 6 5 ---------- then took both to make 4-6 = -2 so -5/2?

yes....the ans. will be -2.5

4. anonymous
