√20×√45=[900]^1/2
[(30)²]^1/2=30,
so it is rational
if u multipy the both numbers u will got 900 so it is perfect square. nd perfect square r not irrational
iseko p/q,30/1 ke form me likha ja sakta hai so it is not irrigational
sorry i irrational
okkk thanks to explan
if it is not a perfect sq then it is irratinal
??
plz answer
tomorrow is my xam
because irrational number ko p/q ke form me nhi likha ja sakta hai , where p&q are integers, example √2ko p/q k form me nhi likha ja sakta jabki p. and q both integer ho aur q doesn't
equal to zero
