What is the value of the square root of 16 squared?
16. The value of the square root of x (any number you choose) squared will always be x.
Why does negative 2 squared equal negative 4?
Because negating a positive number gives a negative number, and squaring any number is always positive. 22 = 4 → -(22) = -(4) = -4. But note: (-2)2 = 4 ≠ -4. It is very important that when giving your question you are clear to where the negative is attached.
Will positive numbers always have a higher absolute value than the negative numbers and WHY?
No. The absolute value is the distance a number is from zero. It is always represented by a positive number. The absolute value of any positive number and its negative counterpart is the same.
Is the absolute value of any non zero number is always positive?
yes
Is the reciprocal of any positive or negative integer always a rational number?
Yes, it is.
In any distribution is the sum of the squared deviations from the mean always equal to zero?
No. It cannot be. Remember that when you square a negative number it becomes a positive number. Thus all squared deviations are positive and their sum must be positive.
What is the answer to -8 to the power of 2?
Positive 64, because any squared number is positive.
Does negative 3 squared equal negative nine?
No. Negative three squared is POSITIVE nine. The square of ANY number is positive, because if you multiply a negative number by a negative number, the result is positive.
Why is any number raised to a even power positive?
A positive number times a positive number is always positive. A negative number times a negative number is always positive. Therefore, any square number will be positive. Any number to the fourth power (a square times a square) will always be positive. And so on.
If you multiply a negative number by a negative number is your answer a negative number or a positive number?
Positive, so any number squared is positive, i.e. -32 = 9
Does -3 squared equal -9?
No, it equals positive 9. Any negative number squared will always give a positive result; the square root of a negative number is always imaginary (a mathematical term, referring to 'i'). So, (-3)2 = 9 and -32 = -9.
Can a perfect square have a negative square root?
If a is any number, then a squared = (-a) squared, so one might say that a and -a are both square roots of a squared. However, the square root symbol always means the positive square root.
Can the area of a square be negative?
not in the real world. The area of a square = The length of a side, squared. Any number squared is positive.
What is 2 to the second power equal to?
-2 squared will be 4. Remember that two negative numbers multiplied will always result in a positive answer. Therefore, any number squared will be positive (except 0 where the result will be 0).
When can the square of a negative number be negative?
This can never be. The square of any number will always be positive. Any positive number multiplied by another positive number will be positive, while any negative number multiplied by another negative number will be positive.
What is the difference between prime number and squared number?
A prime number is a positive integer with two factors: one and the number itself. A squared number is any integer multiplied by itself. With the exception of 1, all squared numbers are composite.
Is it possible to find the square root of a negative number explain why or why not?
This is not possible, because any number squared would be positive, not negative.
