These are three tough Algebra questions that either need to be simplified or solved. Answer as many as you can and I will be sosososososo happy. Thank you.

Question

     

   1. √x(√9-4/3)=√25

 

   2. (4-3*√2)²

 

   3. √135b^2c^3d*√5b^2d

 

        The sqrt symbol in problem 3 is over 135b^2c^3d and 5b^2d

Answer 1

For the first one, is the square root just over the 9 or is it over the 4/3 too?

 

For the second one, you can just treat this like any squaring of a binomial. You would use FOIL. So you should have (4 - 3√2)*(4 - 3√2) and then you just distribute through to find the answer. Use First (4*4), Outside (4*-3√2), Inside (-3√2 * 4) and last (-3√2*-3√2). You then add these together for the final answer.

 

For the last one, it isn't clear what your powers are, can you rewrite them please?
