I have no idea how to do any of this. Assume √ is "the square root of." I will show the whole radical in parenthesis. ^ signifies superscript, usually to the power of
(√6x + 55) = x
^3(√16x) • ^3(√2x^4)
2(√24) - (√50) + 5(√54) - (√18)
(32a^10b^5)^1/5
x^3 + 2x^2 - 8x = 0 (solve by factoring)
x^4 - 2x^2 - 63 = 0 (solve by making an appropriate substitution)
x^5/4
x + 6(√x-7) = 0
:(

| If it's a radical in parenthesis like (√6x + 55) that means everything in the parenthesis is part of the "square root of" |

And neither do I. I do pre-algebra, in 7th grade.

Well I'm in Algebra II
so, what your saying is if there is parenthesis's in a binomial with a square root, it means you square root everything?
Cuz if so, that is incorrect.
Also, if you trying to find x and it's in a square root, you get that monomial by itself and then square it.
Example:
√x = 17
so x would equal 17 x 17
Get it? |

(√6x + 55) = x
assuming you're solving for x
for something like this
square both sides
6x+55=x^2
x^2 - 6x - 55 = 0
factor
(x-11)(x+5) = 0
x= 11 and -5
k.

You got to tell us what you are doing in math. Like what topic, what subject and if you are graphing it or not. You can just give us the problem and let us explain it to you. Because there are numerous ways to solve it, all differently getting a different answer, due to what you are trying to conclude. |

| Sorry, but you happened to choose my LEIST favorite math problems (that is unless these have anything to do with the quadratic formula, I wouldn't know until I wrote it all down in the correct format on paper). |
