Question

Is (√80)/(√720) a rational number? justify

Answer 1

yes it is, we can write √720 as 3√80.(by prime factorization) and hence √80 gets cancelled and 1/3 is left. so it is rational no.
1/3=0.33333...
it's non terminating repeating

Answer 2

Step-by-step explanation:

1. √80/√720

√80/√720

first of all you have to cut both of zero then cut8 as 4into 2 and 72 as 36 into 2 then cut both 2 and 4 as 2into 2 and 36 as 18into 2 then cut 2 and in last it remains 18 so also cut in 9into 2 so the 2 will cut by the 18s 2 and your ans is 1/9 = 1/3
