Final answer:
To evaluate the expression t 2xy^(2) when x=5 and y=4, substitute the given values into the expression and perform the necessary calculations. The simplified expression is 160t.
Step-by-step explanation:
To evaluate the expression t 2xy^(2) when x=5 and y=4, substitute the given values into the expression. Replace x with 5 and y with 4. Then, perform the necessary calculations.
So, when x=5 and y=4, the expression t 2xy^(2) evaluates to t 2(5)(4)^(2) which simplifies to t(2)(5)(16) which further simplifies to 160t.
