How do you do x raised to the 3rd power multiplied by x square?
x3*x2 = x5 Same base so just add the powers
Is x3-27 equals 0 a quadratic equation?
No, it's a cubic equation. A quadratic equation contains, as its term raised to the highest power, a square. Example: x2. A cubic equation contains, as its term raised to the highest power, a cube. Example: x3. A quartic equation contains, as its term raised to the highest power, a term raised to the fourth power. Example: x4. Quintic, x5. And so, on.
How do you solve X9 - Y6 equals X3 - Y2 Between each X and Y power is an exponent?
2x2-y2
What is the answer to x plus y to 3rd power plus x minus y to 3rd power?
(x + y)3 + (x - y)3 = (x3 + 3x2y + 3xy2 + y3) + (x3 - 3x2y + 3xy2 - y3) = 2x3 + 6xy2 = 2x*(x2 + 3y2)
How do you solve this inequality x3 6x2-x-30 Show work for x?
x3 6x2-x-30

How do you solve X3 x X4?
X3xX4=X3+4=X7 this is the correct answer.
What is the answer to x plus y to 3rd power plus x minus y to 3rd power?
(x + y)3 + (x - y)3 = (x3 + 3x2y + 3xy2 + y3) + (x3 - 3x2y + 3xy2 - y3) = 2x3 + 6xy2 = 2x*(x2 + 3y2)
Which is bigger cube or square?
It depends on whether the number being raised to the power is greater than or less than 1. If x < 1 then x3 < x2 If x > 1 then x3 > x2 with equality at x = 1
How do you solve this inequality x3 6x2-x-30 Show work for x?
x3 6x2-x-30
Solve e to the power x equals x to the power 3 algebraically?
ex = x3 This has two solutions: x = 4.5364... and x = 1.85718... Plot the graph of each and you can see the intersections.
What is x to the third power and then to the second power?
That's the same as x3 times x3 which equals x6
What is x to the 4th power plus 6x to the 3rd power minus 2x minus 12?
x4+6x3-2x-12 (x3-2)(x+6)
How do you solve x3 plus 125 is equals to 0?
Realising that 125 is a perfect cube, this is actually pretty easy: x3 + 125 = 0 x3 = -125 x = -5
How do you solve the equation Factorise x3 4x?
X(X2 - X)
