Answer:

46,675

Step-by-step explanation:

So the given expression can be written as:

(81x^2 * y^3 + z)

Given: x=3, y=4, z=19

we have to put each value in the equation above

=> (81(3)^2 * 4^3 + 19)

Among the 'power', 'multiplication' and 'addition', power has the highest priority, so:

=> (81*9 * 64 + 19)

Multiplication has the second highest priority,

=> (729*64+19)

=> (46,656+19)

=> (46,675)
