What are the positive and negative square roots of 4?
The square roots of 4 are -2 and 2.
What is 4 square roots of x equals 8 plus 2 square roots of x?
x=16
What is 16 square roots of 3 times 4 square roots of two?
16*sqrt(3) * 4*sqrt(2) = 16*4*sqrt(3)*sqrt(2) = 64*sqrt(6)
What are examples of perfect square roots?
Perfect square roots are the counting numbers {1, 2, 3, ...} The squares of the perfect square roots are the perfect squares, namely 1² = 1, 2² = 4, 3² = 9, etc.
How do you add square roots to other square roots?
Other than by calculating the square roots and adding the results there is no general method. However, by factorising the number (of which the square root is being taken), the square root can be simplified which may let the square root be added. Examples: √2 + √8 = √2 + √(4×2) = √2 + √4 × √2 = √2 + 2√2 (1 + 2)√2 = 3√2 √12 + √27 = √(4×3) + √(9×3) = 2√3 + 3√3 = 5√3 (Remember that the radical sign (√) means the positive square root.)
What are the positive and negative square roots of 4?
The square roots of 4 are -2 and 2.
What is square root of 4?
4 has two square roots. They are +2 and -2.
What is square root-?
I think you mean square root. The square root of a number is that number when multiplied by itself will give the original number. For example the original number is 4, then we know that 2 x 2 is 4, hence 2 is the square root of 4. We also know that -2 x -2 is also 4, hence 4 has two square roots, +2 and -2 Similarly 9 has two square roots, +3, and -3 Similarly 16 has two square roots, +4, and -4 Not all numbers have such whole numbers for their square roots. For example the square roots of 2 are nearly equal to +1.4142 and -1.4142. Similarly the square roots of 3 are nearly equal to +1.73205 and -1.73205
What is 4 square roots of x equals 8 plus 2 square roots of x?
x=16
What are the roots of the square root of 36x4?
The square root of 36 x 4 is 6 times 2, which is 12. The roots of 12 are +/-1, +/-2, +/-3, +/-4, +/-6, +/-12.
Is the square root of 4 rational or irrational why?
The square roots of 4 are -2 and +2. They are rational because they can be written as -2/1 and 2/1.
Are all square roots rational numbers?
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.
What is 16 square roots of 3 times 4 square roots of two?
16*sqrt(3) * 4*sqrt(2) = 16*4*sqrt(3)*sqrt(2) = 64*sqrt(6)

What two square roots are used to estimate the square root of 5?
The two square roots used are 2 and 3, since 2 and 3 squared are 4 and 9, respectively. Since 5 is between 4 and 9, we can deduce that the square root of 5 is between 2 and 3.
What are the square roots of 4 over 25?
sqrt(4/25) = ± 2/5
