What do you get when you multiply positive 3 by itself ?
(You get 9.)
What do you get when you multiply negative 3 by itself ?
(You get 9 again.)
The square root of a number is something which, when you
multiply it by itself, gives you the number.
When we multiplied positive 3 by itself, we got 9.
So positive 3 is a square root of 9.
When we multiplied negative 3 by itself, we got 9 again.
So negative 3 is also a square root of 9.
Every positive number has two square roots. They're both the
same digits, but one is positive and the other one is negative.
It is positive.
This is not possible, because any number squared would be positive, not 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.
There are two possible answers because if you square a negative number, you will get a positive answer.
The square of a positive number is positive. By the way, the square of a negative number is also positive.
No. The square of a positive number is positive; the square of a negative number is also positive; and the square of zero is zero. If you want to square a number and get a negative result, you need complex numbers. For example, the square of 2i is -4.
Of course it is. 'a' can be any positive or negative number, and 'b' is its square.That's no problem.What is difficult is for 'b' to be a negative number in the same equation.No real number for 'a' can produce a negative 'b'.
The square of negative iota will be the same as the square of positive iota (i.e. -1) because when a negative number is multiplied by a negative number, the answer is positive.
Every positive integer has two square roots, a positive square root and a negative square root. This is because, just like a positive number multiplied by a positive number is equal to a positive number, a negative number multiplied by a negative number is equal to a positive number. Therefore, rounded to two decimal places, the positive square root is equal to 7.28, and the negative square root is -7.28.
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.
If you square any real number it will always be positive.
