Unit 2 Intro (A1CR)

Jeremy determines that  $\sqrt{9}$ =  $9^{\frac{1}{2}}$ .  Part of his work is shown.
 $\sqrt{9}$ = 3 = $3^1$ =  $3^{\frac{1}{2}+\frac{1}{2}}$ = _____ =  $9^{\frac{1}{2}}$  


Which expression or equation should be placed in the blank to correctly complete Jeremy's work?

•  $\left(3^2\right)^1$ 

•  $3^{\frac{1}{2}}+\ 3^{\frac{1}{2}}$  

•  $3^{\frac{1}{2}}\cdot\ 3^{\frac{1}{2}}\ =\ \left(3\cdot3\right)^{\frac{1}{2}}$  

•  $3^{\frac{1}{2}}\cdot\ 3^{\frac{1}{2}}\ =\ \left(3\cdot3\right)^{\frac{1}{2}+\frac{1}{2}}$
