Question

can someone please rationalise the denominators of the following​

Answer 1

Answer:

Step-by-step explanation:

1. 30/(5srt(3)-3srt(5))

rationalising factor=5srt(3)+3srt(5)

30(5srt(3)+3srt(5)/(75-45)

=5srt(3)+3srt(5)

2. 1/(2srt(5)-srt(3)

rationalising factor= 2srt(5)+srt(3)

2srt(5)+srt(3)/17=2srt(5)+srt(3)/17

3. srt(3)+1/2srt(2)-srtr(3)

rationalising factor =2srt(2)+srt(3)

(srt(3)+1)(2srt(2)+srt(3))/5=2srt(6)+3+2srt(2)+srt(3)/5

4.(6-4srt(2))(6-4srt(2)/(36-32)

=(36+32-8srt(2))/4

=(68-8srt(2))/4

=17-2srt(2)

5. (3srt(2)+1)(2srt(5)+3)/11

=6srt(10)+9srt(3)+2srt(5)+3/11
