4. which of the following is the correct notation for 15-sqr-32

5. which of the following is equivalent to sqr-63

Answer 1

See below.

Explanation:

4.

`15 - √(-32) = 15 - √(-1 * 16 * 2) = 15 - 4i√(2)`

5.

`√(-63) = √(-1 * 9 * 7) = 3i√(7)`

6.

`√(-100) + 26 = √(-1 * 100) + 26 = 10i + 26 = 26 + 10i`
