Answer 1

hi mate☺☺☺☺✅✅


take LCM 

LCM (6, 9, 15) = 90
2 and 5 not occuring in pair form

to make it a perfect square, multiply 2 and 5 to 90 (LCM)
90×2×5
900

smallest square number is 900

Answer 2

take the lcm first
30 will be its lcm
now prime factorise it as
30=2*3*5 now u can see all the no 2,3 and 5 is only time so u have to make pair for square as
(2*2)*(3*3)*(5*5)=900 so 900 will be answr
