Question

Write the symbols of the following:

(1) The cube root of 64 is 4.
(2) The cube root of −1000 is −10.
(3) The cube root of −1 is −1.
(4) The cube of root of 8000 is 20.

Answer 1

(1) The cube root of 64 is 4 can be written as $\sqrt[3]{64}=4$
(2) The cube root of −1000 is −10 can be written as $\sqrt[3]{-1000}=-10$
(3) The cube root of −1 is −1 can be written as $\sqrt[3]{-1}=-1$
(4) The cube root of 8000 is 20 can be written as $\sqrt[3]{8000}=20$
