Answer Expert Verified But, negative numbers cannot be inside a square root. So, √-1 is the same thing as. So, the expression equivalent to √-80 is 4i√5.

The imaginary number "i" is the square root of negative one. An imaginary number possesses the unique property that when squared, the result is negative. Consider: The process of simplifying a radical containing a negative factor is the same as normal radical simplification.

Yes, you can square a negative number. In fact, any number at all can be squared, even numbers like pi and 0. This is because to square a number just means to multiply it by itself. ... Note that this is positive because when you multiply two negative numbers you get a positive result.

As shown earlier, a negative square root is one of two square roots of a positive number. For the number 25, its negative square root is -5 because (-5)^2 = 25.

Explanation: To find the square root of 81 , or √81 , we have two find one number, that when multiplying itself, equals to 81 . That number is 9→ (9⋅9=81) Therefore √81=9 .

Other answers show that the square root of 2 (which is approximately 1.414) times the square root of 2, is 2. However, positive numbers have two square roots. One is positive and the other is the negative. That is, 4 has two square roots: +2 and -2.

Negative Exponent If n is a positive integer and a≠0 a ≠ 0 , then a−n=1an a − n = 1 a n . The negative exponent tells us to re-write the expression by taking the reciprocal of the base and then changing the sign of the exponent. Any expression that has negative exponents is not considered to be in simplest form.

This relationship is always true: If you get a negative value inside the square root, then there will be no real number solution, and therefore no x-intercepts. In other words, if the the discriminant (being the expression b2 – 4ac) has a value which is negative, then you won't have any graphable zeroes.

The square root of 2 or root 2 is represented using the square root symbol √ written as √2 whose value is 1.414. This value is widely used in mathematics. Root 2 is an irrational number as it cannot be expressed as a fraction and has an infinite number of decimals.

For y = x^2 - 1, the discriminant equals 0 squared - 4 times 1 times -1 or 0 plus 4. The square root of 4 is both plus 2 and minus 2, so that's why this function has two zeros. For y = x^2 + 1, the discriminant equals 0 squared - 4 times 1 times 1 or 0 minus 4.

Yes. The square root of zero is zero. A square root answers what number times itself equals the target number.
