Question

Tuliskab pecahan pecahan berikut ini dengan penyebut bilangan rasional

Answer 1

1. 1/√2-1 × √2+1 / √2+1= √2+1 / 2-1= √2+1.

2. 1/1+√3 × 1-√3 / 1-√3= 1-√3 / 1-3
=1-√3/-2 = -½(1-√3).

3. 3/2-√3 × 2+√3 / 2+√3= 3(2+√3) /2-3
=6+3√3 /-1= -(6+3√3)= -6-3√3.

4. 5/√7+√2 × √7-√2 / √7-√2
=5(√7-√2) / 7-2= 5(√7-√2) /5= √7-√2.

5. 10/2√3-√2 × 2√3+√2 / 2√3+√2
=10(2√3+√2 / 2.3 -2
=20√3+10√2 / 6-2
4(5√3+2,5√2)
----------------------- = 5√3 + 2,5√2.
