Answer 2

a)√(12²·0.5²) = 12·0,5 = 6

b)√(2.25²·0.04²) = √(1.5)²·(0,2)² = 1,5·0,2 = 0,3=3/10

c) √[(3·16+1)/16]·(2·25+14)/25]=√( 49/16)·(64/25)=√49·4/25)=(7·2)/5=14/5

d)√[(5 si1/6) ·2 si 34/81]=√[(5·16+1)/16·(2·81+34)/81=√(14²/4²)=14/4=7/2

e)√3²·8²·(0,5)²=3·8·0,5=12

f)√[(0,1)²·(0,3)²·(0,01)²]=0,1·0,3·0,01=0,0003

g)√[(3²·5²)/11²]=(3·5)/11=15/11

h)√[(4²·9²)/13²]=(4·9)/13=36/13

i) √[(6²·7²)/0,2²]=(6·7)/0,2=210
