Question

Find three irrational numbers between and 2/5 and 5/7​

Answer 1

Answer:

the answer is

15/35

16/35

17/35

Answer 2

Answer:

If a and b be two given number such that . their product a*b is not a perfect square then a∗b−−−−√a∗b is an irrational number which lies in between a and b.

So here (2/3)∗(5/7)−−−−−−−−−−√=10/21−−−−−√(2/3)∗(5/7)=10/21 will work..

You may verify that 2/3=0.6666667 & 5/7=0.71428571428 and 10/21−−−−−√10/21=0.69006555934 i.e

2/3<10/21−−−−−√<5/72/3<10/21<5/7

also it can be verified that 10/21−−−−−√10/21 is an irrational number .

Again do the same thing taking a= any one of 2/32/3or 5/75/7 & b=10/21−−−−−√

Hope,it is Useful...
