1) 4^2 x (3+5) = 16 x 8 = 128
2) 4 x \(\sqrt{400}\) = 4 x 20 = 80
3) -4 x (4 - 5^2) x -2 = -4 x(4 - 25) x -2= -4 x (-21) x -2 = 84 x -2 = -168
so now can you arrange them from least to greatest?

yep..how do u find the √?

OpenStudy (lgbasallote):
\[\Large \sqrt{400} \implies \sqrt{4 \times 100} \implies \sqrt 4 \times \sqrt{100} \implies 2 \times 10 \implies 20\]
