The inverse of an element \( a \) in a multiplicative group is the element \( b \) such that \( a \times b = b \times a = 1 \), where \( 1 \) is the identity element. For the element \(-i\) in the group \(\{1, -1, i, -i\}\), we check each option:

- **Option A (1):** \(-i \times 1 = -i \neq 1\).
- **Option B (-1):** \(-i \times -1 = i \neq 1\).
- **Option C (i):** \(-i \times i = -i^2 = -(-1) = 1\). This satisfies the condition.
- **Option D (-i):** \(-i \times -i = (-i)^2 = (-1)^2i^2 = -1 \neq 1\).

Thus, the inverse of \(-i\) is \(i\), corresponding to **C**.

C. i

The correct answer is C

llama3.1-405B-Instruct

The correct answer is C. i.

Explanation:

In the multiplicative group {1, -1, i, -i}, the inverse of an element a is an element b such that a × b = 1.

For -i, we need to find an element b such that -i × b = 1.

Since i × -i = 1, we can see that the inverse of -i is indeed i.

Therefore, the correct answer is C. i.

The inverse of -i in the multiplicative group, {1, -1, i, -i} is

A. 1

doubao

C. i

The product of a complex number and its inverse is 1. (-i) * i = -i² = -(-1) = 1.

minimax

The multiplicative group in question is {1, -1, i, -i}. To find the inverse of -i, we need to find an element in the group such that (-i) * (element) = 1.

Multiplying -i by i gives us:

-i * i = -i^2 = -(-1) = 1

Therefore, the inverse of -i in this group is i.

Answer: C. i

D. -i

wenxinyiyan

C. i

Explanation:
The multiplicative group given is {1, -1, i, -i}, where i is the imaginary unit satisfying i^2 = -1.
To find the inverse of -i in this group, we need to find an element x such that x * (-i) = 1, where 1 is the identity element of the group.
Checking each option:
A. 1 * (-i) = -i ≠ 1
B. (-1) * (-i) = i ≠ 1
C. i * (-i) = -i^2 = -(-1) = 1 (This is the correct option.)
D. (-i) * (-i) = i^2 = -1 ≠ 1
Therefore, the inverse of -i in the given multiplicative group is i.

zhipu

The multiplicative group in question is \(\{1, -1, i, -i\}\).

To find the inverse of \(-i\) in this group, we need to determine which element, when multiplied by \(-i\), gives the identity element \(1\).

Let's check each option:

- \( (-i) \cdot 1 = -i \) (not the identity)
- \( (-i) \cdot (-1) = i \) (not the identity)
- \( (-i) \cdot i = (-i \cdot i) = -i^2 = -(-1) = 1 \) (this is the identity)
- \( (-i) \cdot (-i) = i^2 = -1 \) (not the identity)

Thus, the inverse of \(-i\) is \(i\).
