Simplify the square roots

square root of 12
square root of 48
square root of 4/16
4/square root of 5

Sqrt[12]=Sqrt[4*3]=2 Sqrt[3]
Sqrt[48]=Sqrt[16*3]=4 Sqrt[3]
Sqrt[4/16]=2/4=1/2
4*Sqrt[5]/(Sqrt[5]*Sqrt[5])=4/5 * Sqrt[5]

square root of 12 = square root of ( 4 x 3) =2 x square root of 3
square root of 48= 4 x square root of 3
square root of 4/16 = 1/2
4/square root of 5= (4 square root of 5) / 5
