Answer 1

(a)16 (b)-64 (c)-100

Step-by-step explanation

Part A

`\begin{gathered} (-4)^2=(-1*4)^2 \\ =(-1)^2*4^2 \\ =1*16 \\ =16 \end{gathered}`

Part B

`\begin{gathered} -8^2=-1*8^2 \\ =-1*64 \\ =-64 \end{gathered}`

Part C

`\begin{gathered} -5^2*4 \\ =-1*5^2*4 \\ =-1*25*4 \\ =-100 \end{gathered}`
