48 = 4^2 * 3
75 = 5^2 * 3
so that
â48 + â75 = 4â3 + 5â3 = 9â3.

Well â48 is the same as â16*3 which is the same as 4*â3. Likewise, â75=â25*3=5*â3. Add them:
4*â3 + 5*â3 = 9*â3.

Factorise 48 = 16 * 3 = â4^2 .3 = 4.â3
Factorise 75 = 25 * 3 = â5^2 .3 = 5.â3
So you have SQR(3)(4+5) = 9SQR(3) or sqr(243)

48 = 16*3
75 = 3*25
sqrt(48) + sqrt(75) = sqrt(16*3) + sqrt(3*25) =
sqrt16*sqrt3 +sqrt3*sqrt25 = 4sqrt3 +5sqrt3 = 9sqrt3
