Answer:
simplified expression = 16t⁴ - 40t²u + 25u²
degree = 4
Explanation:
The initial expression is:
[tex](4t^2-5u)^2[/tex]To simplify, we can solve the expression as:
[tex](4t^2-5u)(4t^2-5u)[/tex]Applying the distributive property, we get:
[tex]\begin{gathered} 4t^2(4t^2)+4t^2(-5u)-5u(4t^2)-5u(-5u) \\ 16t^4-20t^2u-20t^2u+25u^2 \end{gathered}[/tex]Adding the like terms, we get that the simplified expression is
[tex]16t^4-40t^2u+25u^2[/tex]Then, the degree of the simplified expression is 4 because it is the maximum exponent.
So, the answers are:
16t⁴ - 40t²u + 25u²
degree = 4
