Unit 3 Review

Select all expressions that are equal to 

 $\frac{1}{\left(\sqrt{2}\right)^5}$  

•  $-\frac{5}{\sqrt{2}}$  

•  $\frac{1}{\sqrt{2^5}}$  

•  $\frac{1}{\sqrt{32}}$  

•  $-2^{\frac{5}{2}}$  

•  $2^{-\frac{5}{2}}$  

Solve the rational equation: 
 $\sqrt[3]{x-5}+1=-1$  

Let p=5-11i and q=-5+7i.

What is p-q?

• 0+5i

• 10-18i

• 10+5i

• 25-77i

Let p=5-11i and q=-5+7i.

What is p*q?

 $x^2-4x=-3$  ?

•  $\frac{4\pm\sqrt{16-4\cdot0\cdot-3}}{2\cdot0}$  

•  $\frac{4\pm\sqrt{16-4\cdot1\cdot-3}}{2\cdot1}$  

•  $\frac{4\pm\sqrt{16-4\cdot1\cdot3}}{2\cdot1}$  

•  $\frac{-4\pm\sqrt{16-4\cdot1\cdot3}}{2\cdot1}$  

Which describes the solutions to the equation:

 $x^2-4x+5=0$  

• One real solution
  

• Two real solutions

• One non-real solution

• Two non-real solutions

How confident do you feel about the upcoming assessment?

• I'm ready!

• I sorta ready. I need to do some more practice.

• I feel lost. (If I can, I will practice and email Ms. B if I have questions or want to meet)
