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
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.
What is the value sin x if cos x equals 2 over sqrt 5?
It would be 1 over square root 5.
How do you solve the square root of x divided by four equals 5?
sqrt(x)/4 = 5 Therefore, sqrt(x) = 20 x = ±400
Square root 3 x-5 equals 3?
√(3x - 5) = 3 ∴3x - 5 = 9 ∴3x = 14 ∴x = 14/3
The square root of x-3 plus 5 equals x?
x = 7
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.
Can someone please solve the square root of x plus 5 minus the square root of x minus 5 equals 2?
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
What is the square root of 5square root of 5 square root of 5 and so on?
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
How do you solve 5 to the power x equals 0?
5 ^x = 0 5 = root square 0 5=0
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
X2 plus 4x-1 equals 0?
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
What is x2 plus x-5 equals 0?
x=1/2(-1-square root of 21) and x=1/2(square root of 21 -1)
What is a square root of an number?
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)
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.
What is the square root of negative twenty?
Because the Square Root of negative 1 = i (The imaginary square root of negative 1.) and where if the square root of one number and of another number are multiplied together, the answer is equal to the square root of the two numbers combined. (Square root of 8 times the square root of 5 equals the square root of 40.) So... √(-20) =√20×√(-1) =√4×√5×i =2i(√5) The answer is 2i times the square root of 5. square root (-20) = square root (-1) x square root (20) square root (-20) = i x 4.47213595 square root (-20) = 4.47213595 i
