Question

can anybody tell me about rational and irrational

Answer 1

rational are those numbers which can be written in p/q form where p and q are integers.
example : 4 = 8/2 or 0.5 = 1/2 etc
irrational numbers are those numbers which cannot be written in p/q form
example: squareroot(3) , squareroot(5), squareroot(6), pi etc
squareroot of every nonperfect square number is an irrational number

Answer 2

ok.but is the number\[\sqrt{8+\sqrt{18}}\] is rational???

Answer 3

no its irrational number because
1) 18 is not a perfect square number
2) the whole expression inside the big squareroot is also a nonperfect square number.
thats why its irrational number
