Explanation

L.C.M. of 21, 36, 66 = 2772. Now, 2772 = 2 x 2 x 3 x 3 x 7 x 11 To make it a perfect square, it must be multiplied by 7 x 11. So, required number = 22 x 32 x 72 x 112 = 213444

3x+ 3x+ 3x= ?If x> 0 and x=√(y/x), then what is the value of y in terms of x?If a and b are positive real numbers, then (a0- 3b0)5= ?Where does p lie if p2 (3)5/(3)3=?(-1)2-(-1)3=(√7+√7)2=If x = 4 then -22√x+2=?
