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?
Informally: When you multiply an integer (a “whole” number, positive, negative or zero) times itself, the resulting product is called a square number, or a perfect square or simply “a square.” So, 0, 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, and so on, are all square numbers.

How do you square negative numbers with parentheses?
Enter positive or negative whole numbers or decimal numbers or scientific E notation. When you want to square negative numbers in this calculator use parentheses with your input. For example, to square -4 enter it into the calculator as (-4) with parentheses. To take the negative of 4 squared enter it as – (4) or -4.
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?
Incidentally in English “a negative number squared” would never mean “a negative (number squared)”. It would always be “(a negative number) squared” and would therefore always be positive.
