√x = 5
(√x)2 = 52 square both sides
x = 25
If x equals the square root of ...., then you already have solved for x
No. The Square root of x is not the value of x. So it can not be simplified beyond: Root X + root 3x Yes. The square root of 3x equals the square root of 3 times the square root of x, so when you add another square root of x, you can factor out the square root of x, thereby simplifying the expression to the square root of x times the sum of one plus the square root of three.
It would be 1 over square root 5.
sqrt(x)/4 = 5 Therefore, sqrt(x) = 20 x = ±400
√(3x - 5) = 3 ∴3x - 5 = 9 ∴3x = 14 ∴x = 14/3
x = 7
Yes, because when x equals 1, the square root of x is rational and the square root of -x is irrational, and when x equals -1, the square root of x is irrational and the square root of -x is rational.
First you have to set up a proprtion. 45 over x equals x over 5. Then you get x squared equals 225(45*5). Finally you have to find the square root of 225 which is 15.
root(x+5)-root(x-5)=2 root(x+5)=2-root(x-5) x+5=4-4root(x-5)+x-5 4root(x-5)+6=0 root(x-5)=-3/2 x-5=9/4 x=9/4 +5 x=29/4
It seems to be 25. Call your number "x". x = 5 square root of (5 square root of (5 ...) Square it; this will eliminate the outermost square root sign: x squared = 25 times 5 square root of (5 square root of (... Dividing the second equation by the first one, you get: x squared / x = 25 x / x x = 25
5 ^x = 0 5 = root square 0 5=0
If x equals the square root of ...., then you already have solved for x
Using the quadratic equation formula the values of x are: x = -2 - the square root of 5 and also x = -2 + the square root of 5
x=1/2(-1-square root of 21) and x=1/2(square root of 21 -1)
The square root of an number, is the number that is times by itself to make the product. For example, the square root of 25 is 5 because 5 x 5 equals 25. Or the square root of 144 is 12 (12x12=144)
The square root of a value v is a number x such that, x multiplied by x equals v. Note that -x is also a square root.
Plus or minus the base. If the base is X and you square it, you get X2. If you take the square root of that, you get Plus or Minus X. This is because X*X equals X2 and -X*-X also equals X2.
