What is the fourth root of -16?
Zarrin [17]

Answer:

The answer to your question is 2i

Step-by-step explanation:

                                             \sqrt[4]{-16}

- Get the prime factors of -16

                                                  - 16   2

                                                   -  8  2

                                                   -  4  2

                                                   -  2  2

                                                       1

                                   16 = 2⁴

- Express the -16 as a power

                          \sqrt[4]{-2^{4}}  or   \sqrt[4]{2^{4}i^{2}}

Remember that -1 = i²

- Get the fourth root of -16

                                         2i
