If a number is multiplied by the same number, the result is a square. The inverse of the square is a square root. The concept of square roots extends into the realm of complex numbers when dealing with negative numbers. Here, we will discuss the square root of -96.

What is the Square Root of -96?

The square root is the inverse of the square of the number. Since -96 is a negative number, its square root is not a real number. The square root of -96 can be expressed in terms of imaginary numbers. In radical form, it is expressed as √(-96), which can be simplified to 4i√6, where i is the imaginary unit with the property that i² = -1.

Finding the Square Root of -96

For negative numbers, we use imaginary numbers to express their square roots. Here, we will explore how to express the square root of -96 using imaginary units.

Square Root of -96 by Simplifying with Imaginary Numbers

To find the square root of -96, we first express it in terms of its prime factors and the imaginary unit:

Step 1: Recognize that -96 can be expressed as 96 multiplied by -1.

Step 2: The prime factorization of 96 is 2 x 2 x 2 x 2 x 2 x 3 = 2⁵ x 3.

Step 3: The square root of 96 is √(2⁵ x 3), which simplifies to 4√6.

Step 4: Combine this with the square root of -1, which is i, to get the final result: √(-96) = 4i√6.

Problem 2

If the square root of a negative number is expressed as bi, what is b for √(-96)?

Okay, lets begin

b is 4√6.

Explanation

By expressing √(-96) as 4i√6, we identify b as 4√6, where i represents the imaginary unit.

Problem 3

Calculate 3 times the square root of -96.

Okay, lets begin

The result is 12i√6.

Explanation

First, find the square root of -96, which is 4i√6. Then multiply by 3: 3 × 4i√6 = 12i√6.

Well explained 👍

Problem 4

What is the product of the square roots of -96 and -4?

Okay, lets begin

The product is 8i√24.

Explanation

The square root of -96 is 4i√6, and the square root of -4 is 2i. Multiply them: (4i√6)(2i) = 8i²√6 = -8√6, since i² = -1.

Well explained 👍

Problem 5

What is the conjugate of 4i√6?

Okay, lets begin

The conjugate is -4i√6.

Explanation

For any complex number, the conjugate is obtained by changing the sign of the imaginary part, so the conjugate of 4i√6 is -4i√6.
