How do you solve 9x squared x 81?
9x2 = 81 x2 = 9 <-- Divide both sides by nine x = 3 <-- Square root both sides All in all this is NOT a difficult equation.
What is a principal square root?
The principal square root is the non-negative square root.
Simplify square root of 5 Times Square root of 6?
To simplify the square root of 5 times the square root of 6, you can multiply the two square roots together. This gives you the square root of (5*6), which simplifies to the square root of 30. Therefore, the simplified answer is the square root of 30.
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.
Multiply square root 3 by square root 2?
square root 6
Square root 9x2 y6?
3x y^3
Is this a perfect square trinomial 9x2 12x 4?
Yes, it is the square of (3x + 2). 3x is the square root of 9x2; 4 is the square of 2; to check whether it is a perfect square, the center term must be twice (3x times 2).
Differentiate square root of 1 over 15?
The square root of 1 over 15 is a constant and so differentiating it gives 0.
How do you solve 9 x squared minus 1?
Equation would be 9x2-1=0 Thus: 9x2=1 x2=1/9 x= square root of 1/9 Therefore: x=1/3
Is 9x2-36x 16 a perfect square trinomial?
If you mean: 9x2-36x+16 then it is not a perfect square because its discriminant is greater than zero
What is the domain of f of x equals the square root of 9x the power of 2 - 4?
Since you can't take the square root of a negative number, the expression under the square root must be equal to, or greater than, zero. Just solve this inequality, with the expression under the square root.If I understand correctly, the expression under the root is 9x2-4. For the inequality, get the critical points through an equation first: 9x2-4 = 0; 9x2 = 4; x2 = 4/9; x = plus-or-minus 2/3. Analyzing any points to the left of -2/3, between -2/3 and 2/3, and to the right of 2/3, you quickly see that the inequality is fulfilled for any number that is either = 2/3.
How do you factor 9x squared plus 25?
9x2 + 25 has no rational factors. Its factorisation in the complex domain is:(3x + 5i)*(3x - 5i) where i is the imaginary square root of -1.
Is 9x2-18x plus 9 a trinomial square?
Yes.
How do you differentiate cosine square root of x?
The derivative of cos x is -sin x, the derivative of square root of x is 1/(2 root(x)). Applying the chain rule, the derivative of cos root(x) is -sin x times 1/(2 root(x)), or - sin x / (2 root x).
15x2 - 56 equals 88 plus 6x2?
15x2 - 56 = 88 + 6x2Subtract 6x2 from each side:9x2 - 56 = 88Add 56 to each side:9x2 = 144Divide each side by 9:x2 = 144/9Take the square root of each side:x = 12/3 = 4x = -4
What should be the value of K if 9x square - 24x plus K is equal to a perfect square?
33
How do you solve 9x squared x 81?
9x2 = 81 x2 = 9 <-- Divide both sides by nine x = 3 <-- Square root both sides All in all this is NOT a difficult equation.
