The answer depends on the value of x. The value of x must also be >= 0 in order for the function to be valid in the real number system.

The square root of 5x can be written as:

sqrt (5x) or (5x)^(1/2) or (5x) ^.5

Below are a few examples:

sqrt (5*1) = sqrt 5 = ~2.236 (~ means approximately)

(5*1)^(1/2) = 5^.5 = ~2.236 (~ means approximately)

(5*1)^(.) = 5^.5 = ~2.236 (~ means approximately)

sqrt (5*5) = sqrt 25 = 5

What is the conjugate of 5 square root of 10?

a+ square root of b has a conjugate a- square root of b and this is used rationalize the denominator when it contains a square root. If we want to multiply 5 x square root of 10 by something to get rid of the radical you can multiply it by square root of 10. But if we look at 5x( square root of 10 as ) 0+ 5x square root of 10 then the conjugate would be -5x square root of 10


What is the square root of 25X to the second power y?

5x times the square root of y


How do you simplify the square root of 5x to the 13 power?

The square root of anything to an even power is that thing to half the power. √(5x^13) = √(x^12 5x) = √(x^12) √(5x) = x^6 √(5x) But is that really any simpler?


What is the square root of 25x to the 2nd power?

5x


What is the derivative of square root of 5x?

Derivative with respect to 'x' of (5x)1/2 = (1/2) (5x)-1/2 (5) = 2.5/sqrt(5x)


What is the factor of 25x to the 2nd power plus 1?

(5x - i)(5x + i) where i is the imaginary unit equivalent to the square root of negative one.

If two times the square of a number minus five times that number is 35. What is the number?

If you mean: 2x^2 -5x = 35 then 2x^2 -5x -35 = 0 and by using the quadratic equation formula the value of x is (5-square root 305)/4 or (5+square root 305)/4


What is the square root of 5 square root of 5 and so on?

Call this number "x". In this case:x = root(5 root(5 root(5 root(5... Since the expression inside the first root is equal to the entire expression, you get: x = root(5 x) Squaring both sides, to get rid of the rood, you get: x squared = 5x x squared - 5x = 0 x(x - 5) = 0 So, x is either equal to 0, or to 5. Indeed, if you start with any number and repeatedly multiply by 5 and then take the square root, you get closer and closer to 5... unless you start with zero, in which case you get exactly zero.


What is the solution of 5x the square root of 10 plus 15x?

5x = sqrt(10) + 15x -10x = sqrt(10) x = -sqrt(10)/10 = -sqrt(10)
