Question

(-27)^2/3
write the expression in radical notation
B; evaluate the radical expression

Answer 1

\[\sqrt[3]{-27^2}\]
b. 9

Answer 2

B why is 9 when there is -27 ?

Answer 3

(-27)^2/3
= \[\sqrt[3]{(-27)^{2}}\]
= \[\sqrt[2]{729}\] because (-27) * (-27) = 729

Answer 4

is it \[\huge{-27^{\frac{2}{3}}}\]or\[\huge{ \frac{-27^2}{3}}\]???

Answer 5

729 = 9^3
so
\[\sqrt[3]{729} = \sqrt[3]{9^{3}} = 9\]
