**Algebra II**

What exactly is your question? I don't even see a denominator anywhere :) What you have is right so far. If you want to finish that question you need to use the quadratic formula x = (-b +/- square root(b^2 - 4ac)) / 2a x = (5 +/- square root (25 + 192)) / 16 x = (5 +/- ...

For a right angle triangle the following equation is true: a^2 + b^2 = c^2 Where c is the hypotenuse of the triangle and a,b are the other sides (you decide which side is a and which side is b).

**math**

First you have to expand your terms. 7y^2 - 5y^3 - 180y^2 - 55 = -100 Collect like terms. -5y^3 -173y^2 = -45 now factor the y^2 y^2(-5y - 173) = -45 There are two solutions to this equation. y = 0 and 5y + 173 = 45 which yields y = -25.6

Whoops, the answer should just be x = (4/3)^(1/3) or x = the cube root of (4/3) Bad grammar :P
*February 28, 2008*

**math**

Well 3x * x^2 = 3x^3 So now you have 3x^3 = 4 then x^3 = 4/3 so x = the cubed root of (4/3)^(1/3) Where ^ indicates "to the power of".

**math**

5^3 = 125 So how do we get 125^(1/3) from this? Simply take the cubed root of both sides. (5^3)^(1/3) = 125(^1/3) What then, must the cubed root of 125 be?
*February 28, 2008*

**math**

The "square root" of a number simply means the number is raised to the power of 1/2 or 0.5. So your question becomes (((125)^1/2)^4)^1/6 When you have exponents beside each other you simply multiply them. So the question becomes 125^(0.5*4*1/6) = 125^(1/3) Now what ...
