I am having trouble with these problems if you could help that would be great

Well here they are

1: Simplify

1/ Cuberoot of 64

2: Simplify

√3 √27

-- + ---

√4 √4

3: Simplify

(√7-√2)Squared

4: Solve for X

____

√2x+5 - 1 = x

That is all. If you could solve these or show me how to solve them that would great

1. 64^1/3 = 4 so your answer is 1/4

2. 27^1/2 = 3(3^1/2) so you have 4(3^1/2)/2 = 2(3^1/2)

3. Do you know how to expand (a-b)^2? It's the same thing and you get 7 -2(14^1/2)+2 =

9 -2(14^1/2)

4. rewrite it (2x+5)^1/2 = x+1

square both sides to get 2x+5 = x^2+2x+1 or 4 = x^2 so x = +/-2
