No. The square root of 16 is 4.
The square root of a number is a number that can be gotten by a number being multiplied by itself. Ex = 8 * 8 = 64, The square root of 64 is 8
square root is 8 (8 x 8 = 64)cube root is 4 (4 x 4 x 4 = 64)
There is no square root of negative 8, negative numbers can never be square rooted since no two of the same number can go into a negative number, for example 16's square root is 4 and -4 since 4x4=16 and -4x-4=16, but -16 doesn't have a square root since -4 just turns into a positive when multiplied to itself.
That is because 1x1=1 and to be a square root, a number times the same number, it will be a square root of that number*. *Example 8 times the same number (8) will be 64 and 8 will be the square root of 64.
The square root of 64 is 8
The word square root often refers to the root number of numbers like 64. For instance, the square root of 64 is 8 because 8 x 8 = 64. It's the same with other numbers like 4 (2 x 2 = 4) and 16 (4 x 4 = 16). The symbol for square root is √.
The whole number closest to the square root of 65 is 8. The whole number closest to the square root of 65 is 8.
square root of 8*square root of *4 = 32 Sq root of 4=2 so its 2sq root 8
4 square root of 7
A square root of a number is a number that, multiplied by itself once, will equal the first number. Meanwhile a cube root of a number is a number that, multiplied by itself twice, will equal the first number. For example: the square root of 4 is 2. [ 2 X 2 = 4 ] [ 2 times itself equals 4 ] : the cube root of 8 is 2. [ 2 X 2 X 2 = 8 ] [ 2 times itself, and then times itself again, equals 4 ]
Let's x be one of the numbers, and y the other number. So, x + y = -8 xy = 6 y = -x - 8 x(-x -8) = 6 -x^2 - 8x = 6 multiply by -1 both sides x^2 + 8x = -6 solve for x by completing the square; x^2 + 8x + 16 = -6 + 16 (x + 4)^2 = 10 x + 4 = square root of 10 x = -4 + square root of 10 or x = -4 - square root of 10 if we continue to solve the system of the equations, we can find the same value for y. Thus the numbers are -4 + square root of 10 and -4 - square root of 10. Check: (-4 + square root of 10) + (-4 - square root of 10) = -4 + square root of 10 - 4 - square root of 10 = -8 (-4 + square root of 10)(-4 - square root of 10) = (-4)^2 - (square root of 10)^2 = 16 - 10 = 6
If you mean the square root of (4 x 16) the answer is 8 or -8. If you mean (the square root of 4) x 16, the answer is 32 or -32.
