Simplify of the following:

`root(3)4  xx root(3)16`

Advertisements

Solution

We know that `root(n)a xx root(n)b = root(n)(ab)`.

We will use this property to simplify the expression `root(3)4 xx root(3)(16)`

`∴ root(3)(4) xx root(3)(16) = root(3)(64)` 

`= root(3)(4^3)`

`= (4)^1`

= 4

Hence the value of the given expression is 4
