Is negative 1 squared positive or negative?
The square of −1, i.e. −1 multiplied by −1, equals 1. As a consequence, a product of two negative numbers is positive.
What does negative squared mean?
"This is because to square a number just means to multiply it by itself. For example, (−2) squared is (−2)(−2)=4. Note that this is positive because when you multiply two negative numbers you get a positive result." – This, of course, is the exact opposite of what was asked, but it's the given response.

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 anything to the negative 1 power?
Negative one is a special value for an exponent, because taking a number to the power of negative one gives its reciprocal: x−1=1x.
What does 1 squared mean?
Squaring is multiplying the number twice, so that means: -1 * -1. A negative times a negative equals a positive, and 1 times 1 equals 1, so -12 is 1.

Why is i equal to the square root of negative 1?
Here, the term "imaginary" is used because there is no real number having a negative square. There are two complex square roots of −1, namely i and −i, just as there are two complex square roots of every real number other than zero (which has one double square root).

What is the rule for negative exponents?
In other words, the negative exponent rule tells us that a number with a negative exponent should be put to the denominator, and vice versa. For example, when you see x^-3, it actually stands for 1/x^3.
Is the square root of negative 1 a real number?

Step-by-step explanation: -1^-1 is 1/-1 which is -1.
What does 2i mean in math?
imaginary number 2i is an imaginary number because it has the form 'bi' Remember, 'i' is the imaginary unit and is equal to the square root of -1. Even though 'i' is NOT a variable, we can multiply it as if it were. So i • i gives us i2. Squaring √ (-1) cancels out the square root, leaving us with just -1.
What is i4 in math?
i4=√−14. When we have a number, say √2 and we multiply it by another √2 , we get what's inside the square root sign: √2×√2=2.
Is pi a real number?
Pi is a number that relates a circle's circumference to its diameter. Pi is an irrational number, which means that it is a real number that cannot be expressed by a simple fraction. That's because pi is what mathematicians call an "infinite decimal" — after the decimal point, the digits go on forever and ever.
