## Is a negative number squared still negative?

Explanation: The product of two negative numbers is always positive. If we find the square of a negative number, say -x, where x > 0, then (-x) × (-x) = x2.

## What is the square of (- 1 answer?

Answer. Answer: The square root of minus one √(−1) is the “unit” Imaginary Number. Therefore it doesn’t exist.

**Does negative 1 have a square root?**

Like all non-zero numbers, −1 has two square roots, which we call i and −i . If x is a Real number then x2≥0 , so we need to look beyond the Real numbers to find a square root of −1 . Complex numbers can be thought of as an extension of Real numbers from a line to a plane. The unit in the x direction is the number 1 .

### What is the square (- 1?

Answer: The square root of minus one √(−1) is the “unit” Imaginary Number. Therefore it doesn’t exist.

### Can you have 1 squared?

## How do you calculate a perfect square with parentheses?

Use parentheses to clearly indicate which calculation you really want to happen. A number n squared is written as n² and n² = n × n. If n is an integer then n² is a perfect square. For example, 3 squared is written as 3² and 3² = 3 × 3 = 9. Nine is a perfect square.

**How to take the negative of 4 squared?**

To take the negative of 4 squared enter it as – (4) or -4. When an exponent expression is written with a positive value such a 4² it is easy for most anyone to understand this means 4 × 4 = 16 However, when it is written as a negative value without parentheses the meaning is ambiguous. It has a different meaning to different people.

### Is a negative number squared positive or negative?
