is #1 this??
is just take the squares out of it
you can probably see the rest of this..
Okay so these are the 4 rational expressions that I need step by step answers on:
2. 2√(50) + 13√(200)
3. (rewrite the radical expression in simplier radical form) - I have no idea what that means. 3√(5) (5√(3) + 2√(12))
4. (Solve the equation using your knowledge of radicals) - does it mean to just solve the equation? √(x + 12) = x
sorry it's a lot, these are the four I didn't understand.
The general rule you will apply in questions 1 and 2 is:
For 3: (for a and b non-negative)
For 4: If you square both sides you will get a quadratic equation. At the end you should make sure and hold.
