If you were to do -92, following the order of operations, exponents come before subtraction. Because of this -92 = -(92) which is -81.
The quantity negative nine, squared, however is positive 81. In order to show that you want the entire quantity negative nine squared, you must use parenthesis (or brackets): (-9)2 = 81. This shows to do the "subtraction" first.

How can there be a square root of a negative number?
Square roots of negative numbers are what are called imaginary numbers. The building block of imaginary numbers is the symbol i which is defined as the square root of negative 1. The square root of other negative numbers can be expressed using i. For example, the square root of negative sixteen is 4i, the square root of negative nine is 3i and so on.
How many square roots do negative numbers have?
Negative numbers do not have "real number" square roots.However, they will have two roots (when using imaginary numbers) as do other numbers, where a root including i(square root of -1) is positive or negative.
How do you find the square root of negative numbers?
For most school mathematics, negative numbers do not have square roots. This is because a negative number multiplied by itself is a negative times a negative and so is positive. When (if) you study advanced mathematics, you will learn that there is a solution and this falls within the realms of complex mathematics and imaginary numbers.
Why properties of square roots are true only for non negative numbers?
The square of a "normal" number is not negative. Consequently, within real numbers, the square root of a negative number cannot exist. However, they do exist within complex numbers (which include real numbers)and, if you do study the theory of complex numbers you wil find that all the familiar properties are true.
Why is it impossible to find the square root of a negative?
Because for a number to be a square number it must have a number which when multiplied by it self=that number. For example: 36 is a square number because 6x6=36 16 is a square number because 4x4=16 A negative number such as -16 is not a Square Number because -4x-4=16 not -16 because a negative times a negative is a positive. -4x4=-16 but these numbers aren't the same therefore -16 isn't a square number. This is why negative numbers cant be Square Numbers
Why are brackets needed to square negative numbers on a calculator?
It is due to the way in which a calculator does its calculations. Most calculators follow BIDMAS which stands for; brackets, indices, division, multiplication, addition and subtraction. Since indices are calculated before subtraction, the number will be squared before it is recognised as being negative.
Can negative numbers have a square root?
Yes, but they are imaginary - but are needed in many mathematical calculations. The square root of negative 1 is indicated as the letter "i".

What are brackets in algebra?
There are both "square" and "curly" brackets used in algebra. They are [] and {} respectively in type. Usually square brackets are used to group smaller numbers of terms than curly brackets, and even square brackets are used only to group quantities some of which are in parentheses. Thus a suitable use example would be {[(a - b)(c + d) - a2]/[(fg + hj)/[k(l/m)]}. Larger square brackets are also used to set off numbers in matrix format.
The square of any negative numbers is?
negative always
All positive numbers have two square root a positive and a negative why?
The product of two negative numbers is a positive number. Ergo, the product of the square of a number is equal to the square of its negative equivalent.
How many square roots dose a negative number have?
no,a negative number cannot have a square root .it is made only for positive numbers .but,yes,negative numbers can be squared.
Can you square root negative numbers?
No,because how many times do you have to multiply negative 1 by to get negative 1? You can't do that. Negative numbers don't have square roots. The operation's undefined. Yes, actually you can.
Why don't negative numbers have square roots?
They can, but they are called imaginary numbers. This is because a "square" of something is the number that, when multiplied by itself, will equal the first number. A negative multiplied by a negative equals a positive, and positives can't turn into negatives on their own, so there are no square roots of negative numbers.
Are there any square roots of negative numbers?
imaginary numbers. but no, not really.
What are non examples of real numbers?
The square roots of negative numbers.
