The square roots of 64 are +8 and -8.
Negative
Square root 64 and square root 81
Square root of 64 and square root of 81, perhaps.
The answer depends on what you mean by higher. 81 is bigger than 64. But the square roots of 81 are -9 and +9 while the square roots of 64 are -8 and +8. You then have -9 < -8 so sqrt(81) < sqrt(64) -9 < 8 so sqrt(81) < sqrt(64) -8 < 9 so sqrt(64) < sqrt(81) 8 < 9 so sqrt(64) < sqrt(81) Take your pick!
The square root(s) of 64: ± 8
what is the square root for 64
The square roots of any positive number are the positive and negative number which can be multiplied together to make that number. In this instance, sqrt(64) = ±8.
A number is squared by multiplying it by itself, for example 8 is the square of 64 (8 x 8 = 64). Square roots are found by figuring out which number, when squared, will give the number in question, for example the square root of 64 is 8 (64 / 8 = 8).
64 : -8 -(64) 1/2 32 64 1/2
They are 8 and -8.
The principle square root of 64 is ±8.8.* * * * *The square roots of 64 are +8 and -8.The PRINCIPAL square root is the positive root, +8.So, the answer to the question that was asked is +8 not ±8.
Because two negative numbers when multiplied together make a positive number. Second, two positive numbers multiplied together make a positive number. Here is an example: What is the square root of 64? 8 X 8 = 64 -8 X -8 = 64 So the two square roots of 64 are 8 and -8.
No. The square roots 8 are irrational, as are the square roots of most even numbers.
No. Square root of 9=3. 3=3/1. Therefore not all square roots are irrational
No. Lots of square roots are not rational. Only the square roots of perfect square numbers are rational. So for example, the square root of 2 is not rational and the square root of 4 is rational.
The root There is some confusion on the questioner's part. A root is a root. Numbers have many roots: The square root of 64 is 8 since 8 squared is 64: 8² = 8 × 8 = 64 The cube root of 64 is 4 since 4 cubed is 64: 4³ = 4 × 4 × 4 = 64 The square root of a number x is sometimes called "radical x" because x appear after the radical (or square root) symbol: √x As square roots are used a lot, it is also often abbreviated from "square root" to just "root", for example √2 can be read as "root 2" though to be strictly correct it is "square root of 2". Roots also refer to solutions to equations (linear, quadratics, cubics, or higher polynomials) where they equal 0, for example x = -3 and x = 2 are the roots of the equation x² + x - 6 = 0; x = -2, x = 1 and x = 4 are the roots of x³ - 3x² - 6x + 8 = 0.
