The square root of x-3 plus 5 equals x?
x = 7
Square root x plus 3 equals 12?
X = 81 sqrt(X) + 3 = 12 ( subtract 3 from each side ) sqrt(X) = 9 (square both sides ) X = 81 ( the square root of 81 is 9 )
What is the square root of x equals 29?
Square root of x = 29 can be rearranged by squaring both sides of the equation. That would leave you with: x = 29^2 (or 29 squared) So, work out what 29 squared is and that's what x is equal to.
Which is the best way to solve the equation x squared equals n?
If x squared equals n, then x is the square root of n.
What is the derivative of y equals square root of 8x plus square root of 4x?
y=(8x).5 + (4x).5 = (2+2sqrt(2))x.5 y'=(1 + sqrt(2))/sqrt(x)
Is the square root of x and the square root of NEGATIVE x both rational and irrational?
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.
What is x in 2x2 plus 9 equals -41?
2x2+9 = -412x2 = -41-92x2 = -50x2 = -25x = -5Check: (2*-52)+9 = -41Sorry, you can't have -5 as square root of -25.x = 5i, where i is the imaginary square root of -1
How do you complete the square x squared plus 12x equals 5?
x^2 + 12x = 5 x^2 + 12x + __ = 5 + __ x^2 + 12x + 36 = 5 + 36 (The 36 I got from taking half of 12 and then squaring that number (which is 6).) (x + 6)^2 = 41 x + 6 = (the square root of 41) x = (the square root of 41) - 6. Hope that helped :)
How do you solve for x when it equals the square root of y to the fourth minus y?
If x equals the square root of ...., then you already have solved for x
Square root of a value?
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.
What is a square root of a square?
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.
How do you compute x if x equals negative under root 2?
x=square root (-2) =i(square root of 2)WHERE i2 =-1
Square root of x equals -3?
x = 9
What is the answer to the square root of 8x equals x?
x = 8
Can the square root of x be added to the square root of 3x?
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.
If x equals y can square root x plus square root y equals square root x plus y?
Yes, if x and y = 1 √1 + √1 = √1 + 1 1 + 1 = 1 + 1 QED
What is the square root of x if it equals 7?
49
