Question

URGEENTTT !!!!! 
care e radacina patrata a numarului 324
(1supra2) : ( 1supra 2 la puterea 20) * ( 1 pe 2 la purea 1)

Answer 1

[tex] \sqrt{324} =18 \\ \\ \frac{1}{2} : (\frac{1}{2} )^{20}*( \frac{1}{2} )^{1}= \\ ( \frac{1}{2} )^{1-20+1}= \\ ( \frac{1}{2})^{ 18} \\ \sqrt{ \frac{1}{2} ^{-18}} = \\ \sqrt{ 2 ^{18}} = 2^9[/tex]

Answer 2

 $\frac{1}{2}\;:\;\frac{1}{2^{20}}\;\cdot\;\frac{1}{2}=1/2*2^{20}/1*1/2=2(^{20-1}):2=2^{18}$
