2. What is the square root of 5? - Socratic

   socratic.org/questions/what-is-the-square-root-of-5

   The first few terms are: 0,1,4,17,72,305,1292,5473. The ratio between terms will tend to 2 + √5. So we find: √5 ≈ 5473 1292 − 2 = 2889 1292 ≈ 2.236068. Answer link. The square root of 5 can't be simplified father than it already is, so here is sqrt5 to ten decimal places: sqrt5~~2.2360679775...

3. Is the square root of 5 plus the square root 5 equal to the ... -...

   socratic.org/questions/is-the-square-root-of-5-plus-the-square-root-5-equal-to...

   No: sqrt(5)+sqrt(5) = 2sqrt(5) = sqrt(4)sqrt(5) = sqrt(20) ~~ 4.472135955 sqrt(10) = sqrt(2*5) = sqrt(2)sqrt(5) ~~ 3.16227766 In the above answer, I use sqrt(ab) = sqrt(a)sqrt(b) - which is true for any a, b >= 0. Generalisation Suppose f is a function that takes any Real number and gives us another Real number. Under what circumstances would we expect the following: f(a+b) = f(a) + f(b) for ...

4. Why is the square root of 5 an irrational number? - Socratic

   socratic.org/questions/why-is-the-square-root-of-5-an-irrational-number

   See explanation... Here's a sketch of a proof by contradiction: Suppose sqrt(5) = p/q for some positive integers p and q. Without loss of generality, we may suppose that p, q are the smallest such numbers. Then by definition: 5 = (p/q)^2 = p^2/q^2 Multiply both ends by q^2 to get: 5 q^2 = p^2 So p^2 is divisible by 5. Then since 5 is prime, p must be divisible by 5 too. So p = 5m for some ...

5. How do you write sqrt (x^5) as an exponential form? - Socratic

   socratic.org/questions/how-do-you-write-sqrt-x-5-as-an-exponential-form

   The square root is expressed as an exponent of 1/2, so sqrt(x^5) can be expressed as x^(5/2). Roots are expressed as fractional exponents: root(2)x=x^(1/2) root(3)x=x^(1/3) and so on. This makes sense, because when we multiply we add exponents: sqrt(x) x sqrt(x) = x x^(1/2) x x^(1/2) = x^((1/2+1/2)) = x^1 = x When an exponent is raised to another exponent, the exponents are multiplied: sqrt(x ...

6. Simplification of Radical Expressions - Algebra - Socratic

   socratic.org/algebra/radicals-and-geometry-connections/simplification-of...

   How do you simplify radical expressions? There are two common ways to simplify radical expressions, depending on the denominator. Using the identities #\sqrt{a}^2=a#and #(a-b)(a+b)=a^2-b^2#, in fact, you can get rid of the roots at the denominator. Case 1: the denominator consists of a single root. For example, let's say that our fraction is ...

7. How do you find the square root of 5 to the 3rd power?

   socratic.org/questions/how-do-you-find-the-square-root-of-5-to-the-3rd-power

   Explanation: square root of 5 to the 3rd power can be written as. (√5)3. = √5 ⋅ √5 ⋅ √5. We know that √a ⋅ √a = a. Hence √5 ⋅ √5 ⋅ √5 = 5√5. √5 ≈ 2.236.

8. What is the square root of 5 times the square root of 10?

   socratic.org/questions/what-is-the-square-root-of-5-times-the-square-root-of-10

   1 Answer. Alan P. Sep 10, 2015. √5 ⋅ √10 = 5√2. (assuming only primary roots; otherwise −5√2 is a secondary answer) Explanation: √5 ⋅ √10. XXX = √5 ⋅ √5 ⋅ √2. XXX = √5 ⋅ √5 ⋅ √2.

9. What is the square root of 12.5? - Socratic

   socratic.org/questions/what-is-the-square-root-of-12-5

   Explanation: You can write: 12.5 = 125 10 so: √12.5 = √125 10 = √125 √10 = √5 ⋅ 25 √5 ⋅ 2 =. 5 √5 √5√2 = 5 √2 = rationalizing: = 5 √2 2. Answer link. iOS. Android.

10. What is (5 square root of 5) squared? - Socratic

    socratic.org/questions/what-is-5-square-root-of-5-squared

    And (sqrt(5))^2=5 (it's the square of a square-root, so yeah) Then you are left with: 25*5=125 That's it ...
