ANSWER:

A) Therefore the statement is not true

B) Therefore the statement is not true

C) Therefore the statement is true

D)Therefore the statement is not true

Explanation:

In this case we review each statement to determine if it is true or not

A)


\begin{gathered} n^2\cdot n^2=(n+n)^2 \\ n^2\cdot n^2=n^4 \\ (n+n)^2=(2n)^2=4n^2 \\ n^4\\e4n^2 \end{gathered}

Therefore the statement is not true

B)


\begin{gathered} (2)/(3)-(3)/(4)-(1)/(5)=(1)/(5)-(3)/(4)-(2)/(3) \\ (2)/(3)-(3)/(4)-(1)/(5)=-(17)/(60) \\ (1)/(5)-(3)/(4)-(2)/(3)=-(73)/(60) \\ -(17)/(60)\\e-(73)/(60) \end{gathered}

Therefore the statement is not true

C)


\begin{gathered} 3^3-5^2+4^3=82-2^4 \\ 3^3-5^2+4^3=27-25+64=66 \\ 82-2^4=66 \\ 66=66 \end{gathered}

Therefore the statement is true

D)


\begin{gathered} 19+6-10+z=z+6-10 \\ 19+6-10+z=z+15 \\ z+6-10=z-4 \\ z+15\\e z-4 \end{gathered}

Therefore the statement is not true
