Given that,

The given expression is : [tex]16x^0+2x^2{\cdot}y^{-1}[/tex]

To find,

The value of the above expression when x = 2 and y = 4

Solution,

We have,

[tex]16x^0+2x^2{\cdot}y^{-1}[/tex]

Put x = 2 and y = 4 in the above expression.

[tex]16x^0+2x^2{\cdot}y^{-1}\\\\=16\times (2)^0+2(2)^2\times (4)^{-1}\\\\=16\times 1+2(2)^2\times\dfrac{1}{4}\\\\=16+2\\\\=18[/tex]

So, the value of the above expression is 18.
