a) [tex]\sqrt{36*121}=\sqrt{36} *\sqrt{121} =6*11=66[/tex]
[tex]\sqrt{0,36*196}=\sqrt{0,36}*\sqrt{196}=0,6*14= 8,4[/tex]
[tex]\sqrt{4*\frac{4}{9}*0,0016 }=\sqrt{4}*\sqrt{\frac{4}{9}} * \sqrt{0,0016} =2*\frac{2}{3} *0,04=\frac{4}{3} *\frac{1}{25}= \frac{4}{75}[/tex]
b)[tex]\sqrt{27*12}=\sqrt{324}=18\\[/tex]
[tex]\sqrt{45*20}= \sqrt{900}=30[/tex]
[tex]\sqrt{21*33*77} =\sqrt{53361} =231[/tex]
c)[tex]\sqrt{2} *\sqrt{5} *\sqrt{10} =\sqrt[]{2*5*10} =\sqrt{100} =10[/tex]
[tex]\frac{\sqrt{162} }{\sqrt{6}*\sqrt{27} } =\frac{\sqrt{27}}{\sqrt{27}} =\sqrt{1}=1[/tex]
[tex]\frac{\sqrt{20}*\sqrt{6} }{\sqrt{40}*\sqrt{27} }= \sqrt{10}*\sqrt{9}=3\sqrt{10}[/tex]
Mam nadzieję, że pomogłam.
