1) 2 \*√3 ............2√3 .......... 2√3
------------ ...... = ------------- = ........ ----------
3√3 \*√3...........3*3..............9
2) 2-√2..... \*(1-√3) ...... 2-√2(1-√3).......... 2-2√3-√2+√6
-------- ..... = ..... ------------ ... = ... --------------
1+√3 \*(1-√3)........... 1 - 3.................... -2
------------ ...... = ------------- = ........ ----------
3√3 \*√3...........3*3..............9
2) 2-√2..... \*(1-√3) ...... 2-√2(1-√3).......... 2-2√3-√2+√6
-------- ..... = ..... ------------ ... = ... --------------
1+√3 \*(1-√3)........... 1 - 3.................... -2
2/3√3=2*√3 / 3√3 * √3= 2√3/9
2-√2 / 1 +√3 = (2-√2) * (1-√3) / (1+√3) * (1-√3) = 2-2√3-√2+√6 / -2
2-√2 / 1 +√3 = (2-√2) * (1-√3) / (1+√3) * (1-√3) = 2-2√3-√2+√6 / -2
