Question

a Express 1+√2/√5+√3 + 1-√2/√5-√3 in the form x√5+y√6​

Answer 1

Question 1:

Is zero a rational number? Can you write it in the form p/q where p and q are integers and q ≠ 0?

Answer:

Yes, zero is a rational number. It can be written in the form p/q.

For example: 0/1, 0/2, 0/5 etc. are rational numbers where p and q are integers and q ≠ 0.

Question 2:

Find six rational numbers between 3 and 4.

Answer:

To get six rational numbers between 3 and 4, the denominator must be 6 + 1 = 7

Here, 3 = (3 * 7)/7 = 21/7 and 4 = (4 * 7)/7 = 28/7

So, the six rational can be obtained by changing numerator from 22 to 27.

Therefore, six rational numbers are: 22/7, 23/7, 24/7, 25/7, 26/7, 27/7
