Объяснение:

1)√10*√160=√(10*160)=√1600=40

2)√(1/5)*√(1/5)=√(1/5*1/5)=√1/25=1/5

3)√3*√11*√33=√(3*11*33)=√(33*33)=√(33²)=33

4)√7*√21*√3=√(7*21*3)=√(21*21)=√(21²)=21

5)(3√12+2√3)²=9*12+2*2*3√12*√3+4*3=108+12√(12*3)+12=

=108+12√36+12=108+12*6+12=108+72+12=192

6)(2V2-3V32)^2=4*2-2*2*3V32+9*32=8-12V(16*2)+288=

=8-48V2+288=296-48V2
