Question 78584: this is in an advanced radical equation/multible radical assignment.
this is the problem im trying to solve:
this is what i have so far:
:
subtract  from both sides :
 :
to get ride of the square root i use it on both sides :
then the right side of the equal sign shows :
 =
and this is where i get stuck. How do i solve for the next step?

Question 78511: I am totally lost on the following 3 problems! Could you PLEASE Help me??? Thank you :)
#1 For a home that has a roof that is 7m from peak to eave and the attic space is 3m high at the peak, how long does each of the pieces of insulation need to be? Round to the nearest tenth.
#2Find the distance between each pair of roots.
(-3, 0) and (4, 0)
#3 Use the Pythagorean theorem to determine the length of each line segment. Where appropriate, round to the nearest hundredth.
(3,2) (1,-2)
Thanks again :)

Question 78759: I need to find out what the smallest power to which you can raise both sides of the radical equation is so that the radicals are eliminated.
the equation is:  = 3
I know i need to find a power, but I am not sure how to get it. I don't understand what they mean by so that the radicals are eliminated. I had guessed 3 at first but that is obviously wrong. Can you help me? Thanks.

Question 78774: ok i am doing Graphic representation of radicals of the second order. I am trying to learn how to make squares into a hypotenuse right angle. it say to represent graphically.it says thatthe length of the hypotenuse of a right angle is epual to the square root of the sum of the squares of the lenghts of the other two sides. the first problem is the square of 26.

Question 78900: I need help on solving this, please and thanks!! =)
So far I have this:
I rid the equation of roots by squaring both sides-
Simplified-
Combined like terms-
Divided both sides by x-
Solved for x-
But, when I plug that in to the original equation it comes out to be-
What am I doing wrong?
